I thought I saw an update file for the Predator if using aftermarket T.B./Plenum combo. Actually, I thought I saw this on DiabloSports Web site. I was checking their Web site for the file but couldn't find it?
Hmm, never heard of that. I can't see why they would because their tune is made for a stock car. If you have aftermarket parts you should send away for a new tune or get it dyno tuned.
If that is true though I could use it. I am going to start looking myself.
