I've Brought my Porsche Macan S into the shop on two different occasions for simple oil changes. These guys beat Porsche prices for the service and found other issues with my vehicle. They really know their stuff and I've left with peace of mind each time. Highly recommend!

absolutely 10/10 blew my expectations out of the water. i brought a recently purchased vw in for a faulty sensor, and they were so quick and honest about the diagnosis and cost. they worked with my warranty as well. i was highly recommended by a close friend and i honestly can t recommend peak enough. they sat and had a conversation about just cars in general, and i didn t feel uncomfortable or like i was bothering them at all. genuinely best repair shop i ve ever interacted with, i 100% recommend peak performance for any euro enthusiasts needing help with repairs. thank you guys so much!

Peak and the entire team went above and beyond on my repairs to get my car back on the road. I can't thank them enough for picking up a job that another mechanic botched, and making it right for me. I can't recommend them and their team enough. They were professional, courteous, communicative, and quick. Thank you!

I had purchased an Audi TTS convertible from an out of state dealer that greatly misrepresented the car. unfortunately, they didn't stand behind their car. I almost traded the car due to some mechanical issues that couldn't be diagnosed by other local mechanics. I found Peak Performance & Diagnostics online and called them to discuss the problems. They did a comprehensive review of the car and provided all the recommendations in writing with pictures of the suggested work based on their diagnosis. Joey was great with communication and response. They fixed all the issues and brought the car back to showroom condition. Prices, service and quality was fantastic. Would highly recommend this place to anyone with Audi, BMW or VW vehicles.

This is by far the best mechanic I have been to in NEW ENGLAND, I ve gone to over 5 different mechanics and still haven t received the quality, clarity, professionalism, and care that I received with Josh and his employees over at peak performance bmw, these guys know exactly what they are doing when it comes to fixing German automotive, weather it be simple maintenance, swapping out broken parts, to even adding some of the most brutal performance enhancing parts on the market. Whatever you need done I can 100% guarantee that you will get the satisfaction you are looking for when you hand these guys you re keys. I have been trusting josh with my car for over 4 months now and I could never see myself going anywhere else but here. I can promise you these guys are the real deal, Everyone I ve sent his way has said nothing but positive things and continue to be an ongoing client of his. This guy build cars on a weekly basis that are pushing well over 500-600hp, as DAILY DRIVERS so if that doesn t already say enough I don t know what does, by far the best mechanic around!Services: Electrical repair, Steering & suspension repair, General repairs & maintenance, Auto engine diagnostic, Auto engine tuning, Engine repair, Battery, Oil change

This shop is prompt with responses, completely transparent, very informative, and all around wonderful to work with. They did both performance, and maintenance work on my audi and I couldn't recommend them more! The whole process was clearly laid out, they had an excellent turn around time on the work, and kept me informed along the way, ill be taking my audi here for the foreseeable future.

Josh & the whole crew consistently leave me feeling like my car is always in the best sets of hands when I bring it in for repairs and routine maintenance. My car is (over) 10 years old and they keep it driving like I just bought it from the dealership. I would trust them over a BMW service center any day of the week. I hope to always have a bmw just so I can keep bringing my vehicle to peak performance and have the constant satisfaction of their outstanding work. Thanks guys for all that you do!Services: Transmission, Steering & suspension repair, General repairs & maintenance, Auto engine diagnostic, Auto brake repair, Engine repair, Transmission repair, Brakes, Auto maintenance, Oil change

I recently purchased a 2020 M550i and wanted to get some work done to it. Looked at a couple of places but ultimately decided to go with Peak Performance and I'm glad I did! I had them install a mid-pipe by Dinan. Josh was awesome, super knowledgeable and great to talk to. Their customer service was great, the crew was very cool and their shop super clean. The price was fair and the results are awesome! What else can you want? Thanks guys, I will be back for some more work!Service: Exhaust

Peak Performance & Diagnostics provided Exceptional service on our 2013 BMW 135i. Josh is a pleasure to talk with, very professional, and extremely knowledgeable concerning all aspects of BMW troubleshooting. My level of confidence was immediate. We appreciated the honesty on what needed repair, and what might need attention at a later date. All our future BMW service will be done here at Peak Performance.

I store my E36 M3 at Motorloft (also an excellent business!) in Derry, NH and I mentioned to Tony that my car needed service, Tony referred me to Josh at PP&D and Josh and his team did a fantastic job of diagnosing an engine misfire that two other well known shops could not!Suffice it to say that I would highly recommend this shop to anyone who owns and loves BMWs other foreign exotics!Services: General repairs & maintenance, Auto engine tuning

Can't say enough great things about this business. Josh & his team are super professional, knowledgeable, thorough and friendly. They even send you a detailed list with pictures before you approve the work. My Audi Q5 needed a lot of help and I wouldn't bring it anywhere else. Highly recommend to any Audi owners!

Josh and his team of master technicians have been great to work with. They ve been building my BMW for the last two years and always provide great results. There s no project they can t get tackled from something small like general maintenance all the way to a fully built motor ready for 1000hp. Josh is great to talk to and is always super helpful. Highly recommended these guys for all your BMW/Audi/VW needs.Services: Transmission, Auto battery replacement, Steering & suspension repair, General repairs & maintenance, Auto engine diagnostic, Engine repair, Auto maintenance, Oil change

Peak performance is the best BMW shop out there or any European car in fact, they just did my single turbo conversion on my car to make it 800hp ready and the work is more than beautiful even did more work and never charged me for it, work came out clean and the car never had issues after I got it to them, very honest people and prices are great for what you are getting!!Services: Transmission, Electrical repair, Exhaust, Steering & suspension repair, General repairs & maintenance, Electrical, Auto engine diagnostic, Auto engine tuning, Engine repair, Oil change

Thought my BMW 535 xi had no more life after going to a different BMW specialist these guys made my day by making this car back to road conditions.

Hands down best experience at a automotive shop. The team at Peaks performance was able to help me come out with a single turbo build for my 2008 E90 335xi as it was planned unexpectedly by me.Car wasn t driving at its full potential when I first bought it privately it was taken to a different shop prior and still driving horrendous. the guys just did an amazing job on the build everything I can ever ask for on this platform these guys are more than knowledgeable and helpful.Service: Auto engine diagnostic

The guys over there at Peak Performance are the real deal. I was having all sorts of issues with my e92 335i and a friend mentioned there name to me. I have since gone on a crazy journey with this shop fixing my now incredible e92. The only drawback to the shop is that it has very limited staff. With that being said I was still able to get a hpfp installed as well as my injectors and numerous small here and there s. I m very pleased to say my car is now running as it should and I couldn t thank Josh, Sam, and Cole enough. I would highly recommend this shop to anyone in the area that owns a BMW and doesn t have time to deal with shops that tell you the problem can t be fixed or even worst the stealership . They even took the time to make sure I was happy with what they had done and even while I waited I was able to bounce ideas and questions off of their knowledgeable minds. This is the shop I will always bring my baby too. Without question!!!! Keep up the good work guys you are very much appreciated!!Services: Electrical repair, General repairs & maintenance, Auto engine diagnostic, Engine repair, A/C installation & repair, Air conditioning

These guys did a amazing job on My 2016 F85 X5M after dealer couldn t even figure out what was wrong with my vehicle and another shop misdiagnosing and replacing ecu s for no reason. Peak Performance is here to do good by you and your vehicle, they were able to take my vehicle same week and diagnose just a broken ground cable got me back on the road in amazing time. Wish I took my car there in the first place would of saved me time and money highly recommend themServices: Electrical repair, Electrical, Auto engine diagnostic

Fast friendly and knowledgeable. What more can you ask for. My regular BMW service tech closed his doors and just my luck the following week Joshua happened to stop my work when he noticed my 535i and introduced himself. I didn t need anything at the time but kept his business card in my wallet. Fast forward to two days ago sitting in traffic and the temperature outside read 98 degrees and my climate control was on 67 but it was blowing warm air not cool. Josh had it fixed in two hours and changed my oil too and informed me of some future work I might need. Great guy

Josh and his team are the real deal. Got my car in quick and diagnosed the issue. Needed a radiator replacement. My car was back on the road in less then a week.

The team at Peak Performance know their stuff. Joshua Perrault is an awesome car mechanic. His attention to detail about BMWs is impressive. He went out of his way to explain everything that was done on my E90 335. I would recommend to every BMW owner to checkout Peak Performance if they ever have any issues with their BMW.Services: Transmission, Exhaust, Steering & suspension repair, General repairs & maintenance, Auto engine tuning, Engine repair, Brakes, Oil changeServices: Transmission, Exhaust, Steering & suspension repair, General repairs & maintenance, Auto engine tuning, Engine repair, Brakes, Oil change

Back in October 2021 my Audi RS3 suffered a gouge in a tire precisely in front of Peak Performance. I called them from the street and limped in to their shop for Josh to take a look. The flat couldn't be repaired so he was kind enough to drive me to my house in his truck to pick up my winter rims and tires so he could do a full swap and get me back on the road. While in the shop we talked about future upgrades and he and Cole mentioned Integrated Engineering and Unitronic as paths forward.Fast forward to June 2022 and I dropped off the car for H&R lowering springs with all new Power Flex bushings and an 034Motorsport Dogbone Mount. In July 2022 we pulled the trigger on months of planning with Cole for a full Stage 2 upgrade with Untitronic Intercooler, IE Carbon fiber intake, IE turbo inlet pipe, IE downpipe and IE Catback Valved Exhaust that was expertly installed by Josh.The finishing touch was the Unitronic Stage 2 ECU and Stage 2 TCU tunes and now I'm driving my dream car that was all made possible by Peak Performance. I can't believe how fast and stable my RS3 drives and the sound is amazing.If you need a top notch mechanic then look no further. Go to Peak Performance and they'll take great care of you!
