Turbo Not Pushing

[QIKEXT]

Hey guys i need some help i just got home now and i have a problem, i pushed my R33 gtst tonight and was a cold night but i noticed that first my turbo will debate on weather it will push and kick in but then i later noticed it didnt kick in at all and my motor was doing all the work im running 12psi and have a hybrid intercooler also the car was dyno tuned 2 weeks ago and was running like gold also if i cool it down for 15 mins it runs fine then starts again with the turbo not kicking in its not leaking any boost, it holds boost but just wont push is it the heat??? or what could it be? HELP!!!!

sounds like stock ecu boost cut. turn the boost down a little and try again,. if its a crappy bleed vavle then its just over spiking from the cold weather cos the air is more condensed. the bleed valve has no idea how much pressure is going through so it will just run whatever it "width" is set to. if the ecu see's too much airflow from too much then it does a big timinig and fuel cut to protect tiself. 12psi wil definetly hit it with stock ecu, try 10ish

I can't put the finger on the exact problem. But I had a similar thing happen to me. All I needed to do was tighten my pod filter piping and clean my pod filters. Solved my problem but I'm not sure if my solution will solve your problem.

I would take it to your local performance centre ASAP to better diagnose your problem. Best of luck!

Motec....

Expensive way to go about fixing boost cut. You really should have an aftermarket ecu but... sheesh... powerFC might do for your mods...
