BS3 car falls on its face above 3500 rpm... well im gonna take the car in to be tuned for sure, here is the problem, got the car going with a fast90/nw90 also got the injectors cleaned and flowed by rc engineering, and added an EVAC setup as the PVC was deleted, was blowing out vc gaskets. previously was running fine with ls6 intake and bbk80mm had around 12.1 AFR
Problem:BOGGING BAD, anything above 3500 rpm or 1/4 throttle the tach nose dives and i mean ****** drops and theres no power, but the fuel press stays up oil pres is fine. pulled plugs theyre neither white or drenched in fuel? any ideas needles to say im not gonna run the car till i can take it to tuner but what can i work to fix this before i get there? only made 2 or 3 WOT attempts not full out runs....
setup:
Engine
SLOW
Fuel System
slower.

What do you have for ignition? Peculiar that the tach would
drop rather than justy plateau (like for a fuel or air limited
problem), maybe the ignition box has a kooky rev limit or a
supply, trigger, internal problem? Does tach run off BS3 or
ignition system anyway? Or is this an all-in-one version of
BS3 like I've heard is out now?

Ook so my TPS was damn near falling off fixed that, and tried it out again, now im getting the almost rev limiter type feel above 1/4 throttle if i stay at 1/4 it will climb to 6500 but i throw it in 2nd and it does that bucking type revving, like its hitting a limiter power dies ect.. i mean the car stays on but it falls on its face. my ignition is controlled by BS3. shitty now it sounds liek a fuel problem to me..

Who wrote the file for your car.Is your BS3 new or have you had it up and running for a while.It sounds like your fuel map is screwed up but hard to say without a log file and seeing your calibration.
