Nice seeing some more feedback on this. Yeah, I know that's what it was and how to fix it, my confusion was only in the fact that it suddenly changed and starting rounding my numbers differently on its own.
The only reason I can think of that would cause this would either be (like V said) my hard drive failing causing data corruption (although I find that unlikely, as it happened on my friends machine as well shortly after mine did), or an update in TunerPro probably. Whatever, doesn't matter to me anymore. Roger sold his car, and my Z has a JWT in it.
Dave I saw your post about expanding to the Z platform and others later, and once again, as soon as that is done I'll be all over that like white on rice!
