I've heard about "pinning" the butterflies, but remove them? How's mpg then? Is there sufficient fuel delivery at 7500 rpm with the chip. The SVT still wants to run past the 6750 redline - oooh I hate when it shuts down on me in 3rd gear on the freeway (my SHO would run up that extra 500rpm just nice for instant passes)... so the the chip is my ticket - is there a preferred brand? thanks again.
