Car Not Wanting To Run Over 10psi!?

[jordanlisa69]

so i have a standard bov, poddie, 3inch exhaust off the downpipe, turbotech boost tap, heavy duty dsr coils and new spark plugs.

runs absolutely mint at about 8 or 9 psi but doesnt want to go over it. hit 10 psi and its feels like the car stops accelerating but its still sucking hardcore and just not boosting!

its standard smic

it probly has something to do with the ecu but ive reset it and still doesnt want to go over 10psi

everyone help me out on this please

Sounds like the ecu is telling you your boost gauge is reading low. Be very careful, unless you want a new Garrett.

By the way, my new gauge reads 3 psi over.

haha ive run a aftermarket boost gauge where the standard one is hooked in to so its a real acurate reading.

but what do you mean by that?

There is only so much airflow the factory ecu will allow. Your first mod should be some way of adjusting the ecu, Nistune would be a good option and give instant gains.

The stock turbo wont last long at over 12 psi.

Ecu is retarding your engine. Standard ECU is not designed to run over 10 psi. Gte aftermarket ecu such as MINES ecu, or upgrade to PFC.

You'll find 100's of threads as the factory ECU is shutting down the car - it's what it was designed to do.
