A/F looks like a heart attack. LOL

yeah a heart attacl that coded, did he disable your boost bypass in the tune? otherwise all your boost is bleeding off, and your losing power, those numbers are way too low, if not just manually switch the vaccuum hoses and your boost by pass will be done.

If you have a Stiegemeier Stage IV Port on the blower, you need to add a 4# lower to really bring it to life with the 2.8 upper. It made a HUGE difference on mine. Seems like the older Stage III ports were not a prone to needing the to be spun as hard to produce the torque.

I think that is a canned predator tune with a few adjustments. It is not a custom tune.

I heard that the boost bypass mod bad..... Is that true?

I really don't think the HP matters since you are at the wheel.

ha ha ha thanks...

[sicksnake]

deinitely not it holds the boost so you dont get the evr popular heaton boost dropoff which in turn loses torque and hp. Go get a real tuner to do you a tune the right way and have him turn it off.
