350 vortec on spray
#11
true dat. I have a nelson tune and he locks his pcm so i cant have any body tweak it. But i have a guy who said that black bear doesnt lock his and i can get there tune and have him install it and play around with it to get the best out of it. He has efi live and has done a couple peoples rides.
Besides i have asked nelson to change my AFR and they havnt. I am getting around 14.7 crusin. And barely jumps to 13s at WOT. To lean.
