Dyno numbers from New Era 2.8 pulley package +
That AFR you are talking about is the GM stage 2 tune in comparison on the graph next to our 2.8 pulley tune , not ours , LOL ! Our tune is 11.7-12.1 throughout , and when I say safe I was talking about the timing map in the car .
Thats not bad, good runs and great numbers. After my warnity is up I would like to run a 2.8 pulley and a type of set up. Hell if I'm trapping @ 108 on all GMP set up with a 13.6 and 2.4 60" I should be in real good shape with a tune and smaller pulley with bigger injectors! Good job...will look forward to hearing more about this. Did you say n02!?!?
