Hands down best mopar tuner in the central Texas area. Brought my 2019 RT in with a tuning issue that would cause it to go into limp mode. Issue was diagnosed retuned and fixed within 24 hrs of my appointment. Highly recommend the mopar boys to check them out

Recently brought in my 6 gen Camaro SS since the car was reading codes that said it was running to lean. They had it fixed up within the same business day. Customer service was superb! Super communicative folks and very friendly. I m definitely coming back again for performance modifications!

Procharger website had these guys listed as an authorized installer. I was excited due to the close proximity to me. Everything went smooth and as scheduled. I grinned all the way home in my newly supercharged f250. Woot!

Did a remote and email tune thru high psi performance and he did an amazing job! He fixed my misfire issue I was having and he stayed on the phone with me while doing the start up tune and dyno tuning! Professionalism was 100% and explaining the process made everything go smoothly! Highly highly recommend him for future tuning and will continue to keep him as my tuner!

JD and his coworkers are simply the best! I travel all the way from Houston for them to work on my Charger. Absolutely love JD and the HPP fam. Fair prices and even better work with an entire channel full of YouTube videos to back up the work done here!

Had these guys install an air lift system on my car. Everything works and performs flawlessly. All the employees were extremely polite, professional and definitely knew what they were doing! On top of that the price to get it installed beat every shop in the area. I highly reccomend checking with this shop before going anywhere else and wasting time and money! I will be back in the future to do some of the bigger jobs on my car! Huge thank you to everyone at there at High PSI!

From the phone call to the pick up, Quality Service. Referred by a colleague who was very happy with their work, I made the call to see about some work on my truck and went from there. Made an appointment to get the upgrades done and very happy with how things turned out. Appreciate their hard work, definitely a happy customer.

I have used High PSI Performance for approximately a year now. I have total confidence in JD and his team to service my three vehicles, always professional, honest and fair. They go above and beyond to ensure I walk out the door totally satisfied. No doubt - my go-to Repair Shop.

Scheduled my car to come in and get a tune and it came back perfect and running in way better shape than before! Would definitely recommend to anyone looking to get good work and customer service for good prices as well. Will definitely be coming back for future work to be done.

Great performance shop for all your upgrade / tuning needs! I live in Austin and drive a 21 Challenger, I took it in for a tune after having a few minor bolt ons added. Aida was very helpful and very easy to communicate with throughout the process. I will be returning very soon for more upgrades.Service: Auto engine tuningService: Auto engine tuning

These Guys Did Some Great Work On my hellcat & They were very quick which was the best part. I m Use to shops taking hours or all day to install springs. I dropped it off at 9 it was ready by 1. Thank you guys again I will definitely be back. They also took some amazing shots of my car. Extra points for that.

I took my car to them and my first time was good. But my second time i added a lot more to my car and found they are only good with beginning stages of performance. When i added a lot more to my now race car all the new and upgraded parts they only did a few of them. When it comes to advanced high performance they don't know how.

Went to High PSI to get my 2012 Dodge Challenger SRT8 tuned after a rebuild and several upgrades. On time very professional and very helpful. Took my car and found some issues and corrected them. Tuned her up and very happy. Will have to take care of another issue I have and see how she does. Would recommend to anyone wanting their Mopar tuned.Services: General repairs & maintenance, Auto engine tuning

Took my Cruze to them a few weeks ago for a coolant leak (that I caused). Knowing they re a performance shop I figured they wouldn t be all that involved in fixing it for me. I have big plans for my mustang and wanted to see how they handled the Cruze, and how their customer service was before letting them work on the Mustang (I m particular about who touches it). I have to say, they ve earned my trust. They fixed my screw up, charged me a more than fair price, and came in on a weekend to give me the car back, as I wasn t able to get it sooner. I didn t really think shops like this existed anymore. Justin briefly talked to me about my build plan, and told me what was really necessary, and what wasn t. I respect that. They are the only ones who will touch that car from here on out.

I live in South Austin and drive a 95' Eclipse GST that for the life of me could not find a shop in the ATX area to dyno and tune it for me. I have called countless shops in Austin and they said they did not know how to tune my car, didn't want to deal with my car, and some of those shops were asking for a ridiculous price for only an hour work of tune! Running out of hope, I called High PSI Performance and right away she scheduled me a day to bring my car in. I have had such an amazing experience with the High PSI family and I can definitely say they will be receiving more of my business. I highly recommend anyone in Austin who is looking for a dyno run and tune or any performance work needing to be done to give these guys a call. Though it is an hour drive away from Austin, It's definitely worth the drive for a friendly environment and high quality work. Thank you guys again for treating me and my car with great care and respect. A++++

I order a harness for my ls3, 6L80E trans with 4 pin alternator. So I get 80 % installed and notice they sent a 2 pin. I asked them to send me a 4 pin connector and the wires to go back to pcm. They said we can send connectors but I would have to cut the wrong 2 pin connector and splice wires to the 4 pin connector then I would have to run a hot lead for continues power. Then after that I said send me what I ordered and I will send the other one back, the said it has to be in new condition knowing I already had most the wiring complete. I should have checked but I thought they were professional enough to send the write product,

Hmm.. let's start this long review. 4.3 stars must be genomic buddy related , sure ain't customers experience.. worst experience getting car fixed adding parts ect here at HI PSI. Guy/gal give me price i paid immediate to get things done . Car was not like owner said with mix match push rods (valve) for cylinders was original tsd push rods for torque v4 cam that was originally on the ls3 when I purchased . Just to clear that up. I bought a built motor in town mr Garvin (great guy) ls2 motor so yes I still had the same push rods from original motor ls3 torque v4 cam. So I went in with a issue with ONLY THE CAM AN Check TUNE IT AND DYNO BLA bla blaa.. was told pushrods lengths was wrong to short what ever for the cam small break in cam elgin 1480 sum sum and I paid for push rods . So between that time an finish I thought wth let's do the intake while it's off and went with msd intake. Got sold a water pump I didn't need because if clearing issues on the intake under water pump(could have been shaved) but whatever got water pump paid for an labor get the car back almost month half later supposedly finish to only have coolant leaks an a CEL on which was never present when I drop car off with HI PSI. BTW she's a yellow jacket 04 M6 ONE PIECE DRIVE SHAFT. 9 INCH FAR END PEEDERS COOL OVERS ON REAR QA1 ON FRONT LS2 FORGED WEISCO PISTONS WITH THE BORED OVER. 05 AN A SOLID CRANK.

INTERIOR IMMACULATE WHY WOULD I DO SHITT WORK ON IT. ???.? no i paid for good work and git shitt work. Well let's get back to it.. water pump housing didn't get changed with new a c delco water pump they used old housing which was cracked. An fuel lines on new 1100 msd was ran back to a 3 bend elbow to run back into stock "plastic" fuel line which is notorious for burning up gto's F.O.R.D like ford's. CHECK ENGINE LIGHT *CEL Was bad tune. I WAS GETTING 9 MPG. GOT TUNED TEMPLE SWG GARAGE GET 24.5 MPG CRUISE CONTROL AND FUEL LINES RAN LIKE SUPPOSED AND NEW WATER PUMP HOUSING TO MATCH TO NEW WATER PUMP A.C. DELCO HOUSING.. THANKS HI PSI FOR TYING TO RUIN MY CAR. . GUY AT THE SHOP EVEN BOUGHT MY OLD INTAKE (MEANING IT WAS GOOD JUST WANTED TO UPGRADED.)AND OTHER WARRANTY PARTS TAKEN OFF J.D SAYS HE COULDN'T FIND THEM SO OH WELL WARRANTY PARTS ALSO I LOST MONEY ON THEM AND HIS BUDDY PUT THEM ON HIS GENESIS BUILD.
