Just put Doug Thorley headers (no cats) & a Lingenfelter cold air intake w/100mm throttle body on my '06 C6 Z06. Car picked up 3 tenths & 3 mph in the 1/4 with the mods on the stock tune + the Lingenfelter high & low MAF tables. I have a Ragin Racin Punisher cam to put in over the winter at which time I'll have Bluecat here in KY do a professional tune, but in the short term with bolt ons I'm very close to running tens (11.13 @ 128). I have HP tuners & have already turned off rear O2's, COT & changed fan % temps. Anyone want to give me a few tips on adjusting timing & commanded AFR to try to pick up that extra tenth & get me in the 10's? Normally I would try to comb though the forum & research it myself, but I only have a few days here before my last track outing on Nov 7th.
Thanks,
