Nothing wrong with his car. If he is in Wyoming at 6k+ feet with DA in the 8-9k range the car is taking a serious 25%+ power hit. Would be surprising if it dynoed over 300rwhp up there.
MAP is good, been running his for awhile, but if I had to do it again, would do a flex fuel tune from Lund.
Since I have HP tuners, would be nice if I could just pay a decent tuner to email me a tune and just do a remote tune with HP tuners.
New camaros are pretty damn amazing. Did a twin turbo kit on one last month. No other mods but a setup of twins on the A8 camaro. Laid down 660rwhp/680rwtq. That transmission was amazing. Car was one of the best I've driven.
