Jspeed Tuning

Best Performance shop and tuner EVER!

Went with my brother to Dyno his truck, had alot of fun watching different cars test.

Great place to go for all your performance needs and tuning.

These guys are top notch, JD tuned my newly installed ls376/525 and did a great job this car is screaming now!!! Thnx guys I look forward to working with you again for my next upgrades!

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!!!
