symtoms: everythings seem fines but!!@4000rpm right before my boost kick in it hesitate then @4500 rpm..it push me to my seat @ 5psi..then hesitate again @6000rpm.. look everywhere for vac leak nothing..
again right now all exhaust i have is the main cat after the turbo..no exhaust piping, the little tube beside it is just hanging around..
so i decide to search for my problems...from ..pretty much everything, notice that my ecu code is N327 not N332 like all other TII??? WTF !!!???
can that be part of my problemSSSS????
and my MPG is around 100/ Fulltank ( if i'm lucky)
i'm about to.... myself... help please..

N327 is an NA ECU - why do you have one?!?!?!?!
You're also running 1 piece apex seals, which seal pretty shitty down low.&nbsp Why are you running these???

the ECU came with the car, i didn't notice until i decide to get it out and (was gonna) sent to Cork sport to get it reprogram.
What is wrong with 1 piece Apex???
now that i know..i'm going to get N332 Ecu then see what it does..
But please explain..What is wrong with 1 piece seals??
my original plan is to get Stage 2 BNR then turn my boost to 15-17PSI with upgrade other stuff..

1 piece apex seal don't seal as good as multi-piece designs.&nbsp This means less compression...which means less power...which means more blow-by.

"PROS"- meaning racers? if so that is why they use them because they are never down low.

Gotta agree with ted on his comments. One peice seals are for racing apps where you expect to rip the motor apart every other weekend.

And the N/A ECU won't retard timing against knock and well as has a different fuel curve under vacuum. You need to change that ASAP, and do not drive the motor hard until you do.

BTW: an 88 T2 uses a N333, not a N332 ECU

That 327 (or 326) is an NA ecu, and has no clue what boost is. Throw it far, far away, and get a t2 ecu, n332 or 333. The only diff. between those 2 that Im aware of is an emissions change that doesnt affect running. You can run either one in any s4 turbo regardless of injector resistance etc.
