Quick favor I ask of anyone with an s5 turbo with a stock ecu in working condition.

check it , so I'm haveing a small problem which is turning into a big pain.So the car starts up and runs great, it's a stock turbo II from jap country that i swaped into a 79 sa and i've done all the neccessary work for this bastard to move but it hits 4600-5000 and I'm not able to boost over that rpm.

msd fuel pump w/ max psi 125 but it's set at 45-40 under boost
everythings stock - i took out alot of the emissions crap and smog turd

I've looked at everything , all the sensors that i need are connected, afm is on and tight - i do have a small small crack at the base of the afm that goes a smidge past the fastening clamp but i really didn't think that, that might be the whole reason.

Now i've just resorted to checking the ecu. I'm running the n370 ecu.

SO.. TO THE WHOLE REASON TO THIS POST IS................

i bet some people just scrolled to this ....

i'm wondering if someone can some with an n370 that works let me put it in my car and let me see if it's the ecu or if there is something else wrong. And i'll be able to eliminate one possiblity>>>> if your a yesca head or boooodaahh buddie let me know i got you covered if not and you ask what those two mean then i have no idea what you talking about.

flicks of the car just cause

 

I understand the S5 has a electric OMP that if not connected up will make the engine go into a LIMP MODE. Maybe that's your problem, maybe not.

 

Ya, you do have to have the s5 OMP hooked up atleast, doesn't have to flow anything, just hook it up and put it somewhere.

 

the omp is hooked up i just cleaned out the injectors and they had the worst **** in it all i've ever seen so i cleaned it out and the injector looks great, the car runs better but it still bogs out around 5g s so question

can injectors go bad i could put some gsl-se secondaries if anything

 

ANYONE KNOW IF INJECTORS GO BAD, I think my secondaries have done just that and i'm not able to boost over 5000rpms anyone know whats up.

They get dirty and can get stuck or have diminished spray pattern. You can send out your injectors to companies such as Witch Hunter that clean and flow test them for a decent price.
