I put a post out a wheil back on swapping files. No one responed so I am putting this out there. I have made a few maps now with the new race tuner. I have 3 for 107's 2 for 103 stroker. others for smaller motors but these are the larger ones.I would like to chat with anyone that is currently using the tuner ...... with a dyno to tune. Slow learning curve but puts the PCIIIR to shame. Any one used the S&S one yet??
