If you have a Miata absolutely do not come here the tuner blew up my built motor 1.6 at 210 hp. Then tried to blame the piston company when there is true sign of detonation.

Been with Jspeed for years now after getting my car "built" by ThE bEsT in concord nc. to say enough my car has never ran better and the build continues to improve from having multiple friends go to this shop all have been beyond pleased. I will forever support Jspeed and will prove anyone who goes to that other shop for a cereal box tune that this is the go to shop for LS builds and any type of tuning!!!!

Met JD a couple years ago(IN A RUSH). I was in a slight rush to get my 05 gto fixed up and ready to run right after a few kinks I had to fix with my regular mechanic. Dialed some things in and was ready to get it to a shop. It's a little drive from my home to JSpeed, but once I met JD and realized his knowledge and seeing him firsthand pick up on something before things took a turn, I knew he was a keeper. Solid guy, very high drive to get it right and he did just that with my gto. Ended up putting close to 500rwhp with just a stage 2 cam in a 6.0. That's a feat not too many(if any)can accomplish with the setup I had, mind you I had plenty room to kick it to 530+ with a ls2. I now have a c6 zo6 he actually helped run better as soon as I got it(going from 593 to 610rwhp/on a btr(3) with no added modifications and I'm definitely looking for a wild number going to a stage 4.2. Can't wait!

Try to find a knowledgeable, caring mechanics is so hard to find in Gaston County. Most rip you off big time or cut corners to make "it work".Not this place!They are extremely knowledgeable, and explain everything that needs to be done.I had to have a rebuilt motor (LS1) done for the 3rd time after going to other well known places in Gaston County.They have all failed me and would not stand behind the work that these other places I went to.Now, after 8 years of owning my car and down for 7 1/2 years because of incompetent shops in this area, I NOW have an awesome, strong, fast running car!! YAY!The best part is, is that they have a brand new Dyno which you can have your car tuned or just to find out what HP your car is making. VERY reasonable with their prices!So, if you have a high performance car and need a tune, wanting more HP, needing a rebuild, or just want to see what your rear wheel drive vehicle makes in HP, I highly recommend this place!!!Services: Electrical, Auto engine diagnostic, Auto engine tuning, Engine repair

I have my Camaro at two different shops before I brought it to Jspeed. The first shop I took it to was a mail-in tune, was going to tune and waited two and a half months before I could get it in. I drove 40 miles to get it in there it fouled a plug on number two they wanted a $175.00 to put one plug in so I feel like that was kind of expensive so I picked the car up and took it to somebody else here in Lincolnton. I got a 383 stroker to have it tuned and I had it put on dyno and twisted the drive shaft out, $3000 later to have everything fixed I was stupid enough to take it backso he put it back on the dyno and only got 360 horsepower at the wheels also then he tried to blame it on the dyno machine and blame it on the heads only to find out that the throttle is only opening up 60% paying all that money I put a new cable on it and took it to Jspeed and he put it on a dyno the first thing he noticed was that it the throttle is still opening up only 60% he actually took the pedal out and bent it. I was more than happy to pay him, he said that that went along with the tune anyway he was able to squeeze out 450 horsepower to the wheels was a lot better than the 360 I had and blamed it on the heads I will take my car back to him in a minute he's actually going to put some 243 heads on it and I hope we end up getting 500-550 horsepower at the wheels. He spends time with you after stupid questions that you might ask I well please with him and will recommend him to everybody

After a lengthy search for someone to fix all of my cars aliments Jspeed was highly recommended and so I reached out to the Jspeed team and I'm soooo happy I did. With multiple massive oil leaks and all kinds of demonic sounds coming from the transmission and rear diff. Well let me tell ya. This crew stayed on it and kept a positive outlook on all the worms that came out of the can. My car is like a completely different ride now. So crisp and quite and way more fun than I can say. If you have issues with your LS powered ride, this is the only place to go. Much thanks,appreciation and love for this business. Very reasonable prices, repairs were done quickly. Over the moon happy.Services: General repairs & maintenance, Engine repair, Transmission repair, Oil change

Saved my car from blowing up after Driven so called tuned my car. Drove it once before the idle started doing something crazy. Had my TPS sensor set at 11.1 and 109. Had the pistons hitting the lifters. If you need a good tune and a reliable tune this is the place to go.

After tackling issues with a bad tune and reading the good reviews, I decided to reach out to Jspeed. I m glad I did. Super great place and people. It was really hard for me to find someone with the knowledge and patience to tune my gen 3 ecm. JSPEED was the place. I recommend them. It s really nice to be able to drive my car without any hiccups or fear about a embarrassing erratic idle or stalling. . It was also REALLY NICE to be able to talk to my tuner and ask questions and get insight on what I need to do and shouldn t do. I could not get that any where else.Service: Auto engine tuning

I took my 08 Corvette to Jspeed Tuning after doing an F-35 cam swap. Not only did JD give me advice on the swap as I did it myself but he did all the tuning and this car is a rocket ship. Not only does it make a ton of power, but it is very mild mannered on the street which speaks volumes to the skills that JD brings to the table when it comes to tuning and building cars. If you re looking for a reliable and fair shop to get your car tuned at, look no further. I can t recommend Jspeed tuning enough!

I was sweating going anywhere but the one LSX shop everyone knows, and waits on, based on word of mouth and recommendations. I went out of my comfort zone and tried one of the newer kids on the block and boy am I glad I did! JD is very professional and knowledgeable and took the time to explain everything that was wrong and everything that he was doing to remedy the situation. ONE HOUR on the laptop and my car is night and day better after having spent thousands on a "pro" dyno tuner before with poor results. My car is a 2015 Z/28 and is by no means a simple vehicle. My complaint was drivability with the big cam, not power, and that's exactly what I got. JD and his crew know what they're doing and I look forward to becoming a repeat customer and watching the shop grow. Highly recommended!Service: Auto engine tuning

JD did a great job tuning my parent's 2008 Pontiac G8GT! He was able to determine there was an issue with spark knock and quickly narrowed it down to improperly torqued and bad spark plugs. He changed them for us and did a dyno tune on the car. It idles much smoother now, has much more linear power, and the transmission shifts so much better. He did a phenomenal job, and I cannot wait to have him tune my 6th gen Camaro once the warranty runs out and I add a few goodies to it.Services: General repairs & maintenance, Auto engine tuning

My husband, Bob, took his 2005 GTO to Jspeed to be retuned because the original tune had drivability issues. JD did an outstanding job fixing the tune, eliminating all the issues. My husband was so pleased with the tune that he had Jspeed install a torque converter in his 2009 G8 GT. JD also tweaked the engine tune, picking up 30 hp, and he adjusted the transmission tune for better shifts. The guys at Jspeed Tuning do outstanding work and Bob will not take his cars anywhere else!

First and for most I think these guys are some of the best in the business!! I work a very strange schedule and the people at J Speed Tuning were able to get me in after hours. They ve been over backwards to make sure I m satisfied. Some of the best work I ve seen done. I would recommend anybody to go to that shop. I will continue to do business with them and only them from here on outServices: Exhaust, Auto engine diagnostic, Auto engine tuning

Jd and his mechanics know their stuff and handle your car with competence and care. My supercharged c5 z06 made 640whp on their in-ground dyno jet. They specialize in LS and chevy applications but will also work on other domestic (Ford and Dodge) and euro/import builds.

Jspeed fixed all three tunes on the vehicles I brought from Texas and even pointed out the things he saw wrong. A big Turbo C10, NNBS cammed and future turbo build, and a cat eye 408 stroker.Services: General repairs & maintenance, Auto engine diagnostic, Auto engine tuningServices: General repairs & maintenance, Auto engine diagnostic, Auto engine tuning
