VADER SS L99 · 12-09-2014, 12:48 AM

Anyone ever see a ZL1 running in the 13's or not exceeding 110mph at the drag strip? I think it might be the same problem with the LT4. It's probably heat soaking easily and getting really high IAT's thus killing tons of power. I seriously don't think that's a factory tune issue. If the IAT's are soaring a tune isn't going to fix that and if you go soft on the IAT tables then you could be looking at a hurt engine unless you use some sort of race fuel or E85.
