These are great people to do business with I had a email tune done on my 2011 camaro. After having two other people and myself try to get this car driving right these guys nailed it down it just two tune files. Car has a decent sized cam for a street car and it drives so close to stock if not for the idel you wouldn't even know it was camed. If your on the fence about working with these guys just do it you will not regret it.

After dealing with many different speed shops in NC. I can honestly say hands down. PCM of NC, INC is the best. Customer service. Reliability. Communication. Parts. Staff. Tuning. You name it. It’s mind blowing how above and beyond they go for their customers.
Keep up the great work!

My visit to PCM of NC was amazing and a pleasure. Always great customer service! But it's just a different kind of energy why car folks get together and start talking cars.

What fantastic customer experience, I did a mail order tune and was communicated with every step of the way. The truck drives awesome now. Really stand up people.
