what could be the problem(4000-4500rpm)
 

k so i dunno whats the deal, its not that big, jus wondering

so im stage 1 now...

when i hit around 3rd gear, around 4000-4500rpm, it'll hit full boost but it has a hard time and goes really slow going past that... same in 4th gear

if im not hammering on it, its fine...

i must let u know that earlier we turned my Vortech down from 12:1 to 6:1, we changed the plates....could that be the issue, i dont really know what a rising rate regulator does.

i was jus thinking that since its stock injectors it might jus have trouble flowing lots of fuel, but since i dunno what a R.R.R. (vortech) exactly does, i figure i'd ask

Maybe you're too lean or too rich? What's your AF gauge doing?

my narrowband a/f gauge isnt working...the narrow band gauge is crap n e ways jus goes back and forth...back and forth...

If you'd be running too rich or too lean than you could loose some power. Check your spark plugs. You should be able to see if they are white or black.
