If I wanted to do warranty compliant (or rather "tolerant") bolt-ons, what can I get away with so the car will still "run" when I flash back to the factory map? For now, ideally I'd like to do: Chip+Tune \ CAI \ Headers + High Flow Cats \ Rear exhaust \ Injectors \ Pulley(s) \ Blower porting + intercooler (in that order).
But from what I am reading I'd have to stay somewhat conservative with the injectors. The guys at my dealership said that GM can get a little sticky on Headers and Cats, and that its better to modify the back half of the exhaust system if you are going to change anything. I am also looking at feasibility of a Z06 or LS9 clutch assembly, to reduce rotating weight.
We just recently installed a corsa axle back and an airaid cai on one of our demos and it helped quite a bit. Not sure what the numbers are, but you definetly tell a big difference in the seat of your pants!
I don't believe the clutch assemblies are interchangeable.
Sorry, why are we starting at 450hp? Does the V put out 556 on paper but only 450 on pavement?
