I bought a Predator for my 04' Z. I'm running just an X-pipe and a Honker CAI. I'm convinced that with the Predators basic stock tune, the car is SLOWER. Are there any other numbers I can mess with safely to get my money's worth out of this $400 computer?

This will get you in the ball park.

I have a Predator and don't use it anymore.

Just getting statred is a big problem and the instructions above were a big help to me.

Good luck with yours.

I bought one of these units but sent it back when I realized that you can not alter a pre-existing program with it as the ad I read somewhat implied. That little lesson cost me a 20% handling fee ($65!!!). Live and learn.

WOW Great info . I have an 04 A4 and love my Diablo predator.

Predators help automatic trans C5 the most.

But the only way to determine if your's is better or worse is to do some before and after 1/4 runs and compare time slips.

Guess that depends on what you want to alter. You can modify both the factory and the performance tune.

yes, should have invested in hptuners

The problem was I wanted to ckeck and adjust a custom tune by a local tuner. I was having fuel mix issues, too rich/lean, maybe tweek fans, which took multiple trips back to shop, 100+ plus miles round trip. I actually bought a predator because the advertisement stated that it accepted custom programs. I thought that I would be able to adjust the existing custom tune. One of the first thing the instructions say is that is does not accept a non-factory tune. I returned it but that little lesson cost me 65$!!! Just another paid lesson...

Look into a software program like HPtuners or EFIlive. They both offer much more flexible and precise tuning for almost every parameter/table in the PCM. The initial cost may seem high, but once you use one, you will never look back.
