enough fuel???

[nazthug]

I have a 99gst with :

RRE upper IC pipe
greddy bov
thermal 3" catback
2.5->3" downpipe, no cat
evoiii o2 housing
injen intake
bcs nipple mod

Currenty it boosts over 15psi but comes right back down as you keep on it.

Am i still good with the stock fuel?

Im boosting too high, i would like to lower my boost, how can i do this?

I have a profec b waiting to go in, but it wont really let me go lower on boost unless something else is changed, i would like less boost in 1st gear.

ALSO, if i upgrade my smic to a dejon or adfx, it is much more efficent, drop of is like 1 psi vs 4psi, so now im gonna be making even more boost????

Does just adding a 190lph pump without any other tuning allow more the ecu to add more fuel???

I heard you can get 510cc injectors and not have to get a afc?

Will that be enough for a t28 as well?

I rather not get into the wiring/tuning of the afc, i've done too much tuning on my old car(turbo focus with standalone) and i just dont wanna get that deeep into it, although i am willling to change a fuel pump and slightly larger injectors

The stock t-25 turbo does not hold boost well in the upper rpm ranges. Around 6,000 rpm's the boost starts to fall to around 13 psi. A boost controller will not make a difference because it is the turbo that cannot maintain the boost. You will be able to get more boost out of the turbo with the profec b, but it will still fall off at the upper rpm ranges. No matter what, boost will not hold to redline. You will only achieve more boost at the lower rpm ranges.
