Who recommends a good chip that will make sone decent gains for the V8. It's hard to believe that no one makes a good chip for this car. Anybody shed some light on this? Lot's of stuff for the 2.7t..but that does me no good. I plan on the following:

Catback Exhaust with Downpipes
K&N Cone filter (Inside existing airbox)
Tranny Chip - APR

I dont want to slam supercharger on this thing. Thanks in advance.
