i'm confused as to how the inj duty cycle is lower on a smaller pulley? More boost=more air yet the injectors have to work less to compensate, that doesnt seem to make sense to me?
Info please!

water/meth injection is a wonderful thing to have on these cars.
im ordering my kit here shortly actually, not as a power thing, more or less as an added cooler.
the duty cycle is lower due to the fact the car is running leaner. more boost does not always equal stupid high duty cycles. the stage 2 on 91 octane in my car was reading 10.5-10.6 at the tail pipe.
with the 2.8 with the tune i have right now it is reading 11.0 at the tail pipe. duty cycle per "hp tuners" is reading 7% lower. it has to add less fuel, which in short, makes the % lower.

I don't know much about tunning. Since I have GM stage II, CAI, GMP manifold, and GMP exhaust would a tune from a prof. give me more power safly? Or, the way it is now working fine? I don't see how GM would have a reflash for Stage II and keep a warnity if it was not safe.

basically, run the highest octane you can in the car, 93-94-100, whatever it may be. get a light tune done, nothing major is needed aside from that in my opinion. of course, others have different views
