Tune Adjustments for Diablo Predator

**Red Chevy** · 01-15-2007, 09:59 PM

OK, I need some help please. Does anyone have a specific list of parameters they changed their diablo performance tune to? I have a '02 SS with LT's, Y pipe, no cat's and the Diablo performance tune is on the car already. I'm trying to see if anyone adjusted that tune? if it makes a difference I live on the east coast, MD. Any help will be appreciated.

I also have a 2000 Z28 with bolt-ons. I used the Predator and installed the Performance Tune. Are there proven parameters any of you LS1 folks have manually installed with good results (don't want to injure the engine)?

i upped the WOT trans pressure, and decreased the shift time alot. so far ive been real happy with the way the trans mission is working. other than than the diablo sport the trans is stock.

i cant tell the difference in the torque management stuff though

Not to hijack this post, but I would also be interested. I am thinking of buying one. Looking for any dragstrip comparisons, back to back?
Looks like a nice piece, but I am still skeptical,,,I haven't seen much gain in the past with handheld tuners.
