SR20 HELP! (video included)

[Ambush]

i have NO idea what is wrong with it.
at first i thought it was the ecu. i tryed another ECU (red top) everything is still the same.

in the video, the popping sounds and stumbling sounds are backfires.
the car struggles to go pass 3000 RPM.
my turbo spools up to quick, and it just stays at boost.
its like im only getting 50HP.

have you tried swapping out your MAFS for a known working one? maybe your car is in limp mode and dumping lots of gas

check your MAF

MAF...check ECU for codes...vaccuum leak

[s13silvia123]

boost leak check for that

[Ambush]

i've changed the MAF. tryed a red top & black top ECU.

vaccuum leak will cause you to run pig rich and give you major trouble revving....check all your lines...10 bucks says you've got a leak somewhere...check IC piping/IC...everything...it's there somewhere

? What else do you want. We've given you a list of the most likely causes. Go check over every square centimeter if you have to.

Hows your CAS timing? Too retarded will cause the turbo to spool up quick and your car goes nowhere. Happened with my friends redtop, we turned the CAS almost all the way clockwise and it ran like a champ after that. But it sounds like a combination of that + vacuum leak somewhere.
