Are you planning on running the 2.78 with the stage 2 tune? Cause I'd be worried about running lean.

isn't that what a lot of the stage 2 guys are doing because it runs so rich otherwise?

Yeah, but I've heard of guys running 100% duty cycle on the stage 2 injectors and a 2.79 pulley.

I have the 2.79 pulley sitting on my desk in front of me, I plan to run it on the stage 2 tune with the 42.5lb injectors. If it runs like crap, I'll put the stage 2 pulley back on.

.01/.02 inches isn't going to make a huge difference. there are people running 2.8's on the stock injectors.

2.8" pulley + Stock injectors = 115-120% duty cycle

16 psi is like a 2.8 pulley....that wouldn't be a bad idea ^^^^

But imo....I would just save up for 60 lbers and a 2.6 or 2.5 hehe
