just wondering how much hp i can make my 88turbo on 3''dp 3''testpie 3''exhaust,fipk intake vpc gcc evc,everything else is stock,what do you guys say,also a 32x12 fmic with 3'' pipes,thanks let me know what you think
how much hp can i make on bpu with vpc gcc evc

With stock electronics/fuel you usually end up running in to a wall in around 300rwhp due to fuel cut. A little higher maybe, but not much.
250whp 280ftlbs at 10-11 psi, maybe more.
My old 91 did 256/274 11 psi 3" exhaust and an intake, no tuning.

Yes sir.
Big power requires more boost,
more boost requires more fuel.

It does.
Personal experience seeing the VPC's KV frequency signal output never going above what would trigger FC, plus many years of 20-30psi pulls on several Supras.

It's likely the table in ROM doesn't have a value above FC.

It depends on the setup. A stock injector rom and a upgraded turbo with upped boost will either hit fuel cut or go lean if the rom indeed doesn't have values above boost cut. It cant bypass the ECUs programming.
With a 550 rom with 550 injectors it changes everything, but I assume hes on a 440 chip since he made no mention of upgraded fuel.
all i have is a walbro 255lp upgrade everything else is stock,the vpc has the 550chip but i obviously cant run 550 chip with 440 inj so i have the 440 chip that im going to put in

It will not trigger fuel cut because the VPC is configured to not output a KV signal high enough to. It may run lean if VE moves too far beyond the mess of a fuel map that results from the combination of the stock ECU and the VPC. That is why I stated it needed careful tuning. In most cases the stock fuel map is extremely rich. 440cc/min injectors can support quite a bit more than most think.
What exactly does EVC and GCC stand for? i know its a Boost controller/Extra tuning for the VPC..

It doesn't matter how much the 440s support its how much the ecu will give before fuel cut. You're limited to the stock ecu.
But this makes me wonder, what kind of Duty cycle does the stock ecu run before fuel cut. It would seem as its not a static number through out the whole range, but it increases with rpms.
