my bad on the fuel milage and performance, I forgot that I had other issues at the same time I put the headers on.
As for the Predator, What exactly can they do, cause I thought they were only slightly more advanced then the Hypertech. Either way. The important thing to emphasise here is that if you do get a SES light, don't take it to Autozone, take it somewhere where someone will understand what you have had done on your car and be able to correctly identify your problem. Many codes come up as emmissions stuff and I just wasted money on two brand new O2 sesors trying to isolate the problem, which in reality there never was one. Thanks for correcting me

 

The guy that I bought mine from has software simular the LS1 edit at his shop so he can make any changes that I desire and e-mail the revised program to me. I hook the Predator to my computer and load the new program in then take it out and load it into the car.
And comparing a Predator to a HPP3 is like comparing apples and red meat.
A Predator can do anything that a HPP can do plus spark timing changes, WOT fuel changes, a much finer control of the other parameters, it's a live data scanner, and it can read and clear trouble codes.

 

oh ok, i hadn't thought of using the predator in that way. Thats pretty cool
