ok first question.. what octane gas are you running..

second thing. i have heard that some cars go lean with the canned preditor tune and don't respond too the contorls too richen it up a bit.

if you are using 93 octane and still have a issue i would go back too the stock tune untill you can get too a dyno and run widebands on it..

Download the latest revision r50d into the Predator and see what it does before adding timing or adjusting fuel.

The custom tune I have will not work on your car because:

I have a different ECM
I have a different MAF setup
My base timing is different

It was $75 for unlimited tunes from www.injectedracing.com, for which I sent my stock program copied from the Predator, dyno session info, and some Predator datalogging info regarding MAF voltage versus rpm while on the dyno. My A/F was very lean at WOT with the stock tune due to my exhaust and CAI mods, but the custom tune got it to a virtually flat 13 and gained some HP. The turnaround time on e-mailing the tune was less than 24 hours. In other words it was worth it.
