Hi Folks
I have wrenched and races cars since the late 1960s and have owned Corvettes since 1975
For many years raced them in many formats

Been custom PCM/TCM tuning since 1995 as back then racing a 1994 ZR-1 and there was no tuning tools to allow
making calibration changes for different types of racing, elevations, etc I needed

Ran into John of Tunercat in 1995 and have mostly used his tuning tools for OBD-I and II

Have a great and fun summer this year !
