read my stock tune a couple years ago and had it tuned.
later i went back to stock and got a trifecta tune.
today i went back to stock from trifecta and tried to flash a modified version of my stock tune that i altered myself with the same hpt module that i used before but now it says the "File OS ID does not match VCM OS ID".
whats going on? could the trifecta be messing it up?
for some reason it wont let me attach a .png screen shot.
