Customer Testimonials

I contacted PCM of NC to get a email tune for my 2014 Corvette after installing a A&A supercharger. The part of the country where I live the closest reliable tuner is 8 hrs away round trip plus he wanted me to leave my Corvette for a few days. With the help of PCM of NC my Corvette is running really great. I highly recommend them. All emails were quickly replied and turn around times from data logs to new tunes was in less than 24 hrs. Fast emails great service from PCM of NC makes them the best choice. I'm a happy customer you could be too just email them..

WOW!!! My H3 Hummer runs like It has a new engine!!! Best upgrade I have done so far. Thanks PCM of NC

Had a 100% positive experience with PCM of NC! Did an AFM/DOD delete on my 2012 Silverado. Shipped the ECM on Tuesday afternoon and it arrived back to me Thursday morning. Had several questions for their staff and they answered all of them quickly and thoroughly both over the phone and by email. Thank you!!

Just spoke with Mark from PCM of NC super nice guy answered all my questions and was extremely honest with me about a service and recommended me to 2 other companies that were able to help me completely. Would absolutely recommend in the future.

I've been using guys from pcm of NC for years for all my tuning needs and always have been helpful on my questions and concerns. Tunes always work great. On my tbss and my c5. Thanks pcm

Just recently got a tune for a 4.2 vortex inline6. Very pleased also they updated the PCM before turning and it fixed a intermittent problem I was having with reduced engine when cold out the best part now I have traction issues 😁

Amazing pcm tune for my 2007 hummer h3. Extremely fast service for mail in. They sent it back the same day they received it! Test drive is a word of difference in throttle response, shifting, etc. Thank you pcmofnc!

Ordered an electric fan conversion harness for my truck. Got immediate notification that there was about a 1-2 week lead time on making them because of supplier issues. Contacted support to make sure I was ordering the correct harness and they responded quickly via email. Part arrived yesterday(only 5 days since I ordered). Awesome service and part installed without issue. I was replacing an already installed, sub-par harness, so I didn't need to follow the instructions closely, but the instructions included were detailed and easy to follow from what I saw. Thanks again and I will definitely look here first before making any future purchases for my vehicle.

I'm from the UK but I own a 2014 Camaro SS and the support over here is pretty much zero so for things such as tuning its a better idea to use someone in the USA that works on these cars day in/day out.

The people over at PCM of NC are great, very responsive and they always answer all my questions that I had through the process of tuning my 2015 Camaro. 100% recommend them for any work you may need. They are extremely knowledgeable and do great work. I only have high praise from my experience with them. Extremely satisfied
