Mail Order Tune

Went great had a problem with it still not starting after getting it back called them told them my issue they told me to hook my MAF sensor up since that’s what it’s tuned for and it fired right up really appreciate them. Will definitely be going through them again on my next build

I have a 2007 Chevy avalanche 5.3 I had the dreaded valve collapse and decided to replace it with the mellings cam and valve kit. At the time, I didn’t realize I had to reprogram the ECM. After it was all installed I went online to find out where I could get my ECM reprogram. I couldn’t be more happier with their work I unplugged mine and mailed it to them and I had it back in four days. It plugged right in and fired right up. I’m extremely happy. I would highly recommend this to any of my friends. Good luck with your projects Tim.

I did a DOD and VVT delete and also installed a chopacabra cam on my 5.3. I shipped my ECU to get tuned. They did an amazing job with the tune. And they also assisted with questions I had. The shipping was extremely fast ! It shipped out the same day they received it. Great customer service and great tuning !! Thank you
