Hey .. Its me again, with a new problem to share with you lol

here the symptoms

1. the engine have some difficulty to idle ( 600 to 900 ) but not everytime2. if i stay under 0 bar on my boost gauge the car run fine, but if i press to much the throttle, the car is cutting and doing this kind of sound : bucbuckbucbuck( + random backfire) and the rev doesnt go higher.

I took out the ecu code and its 55, its not sensor related. That make me think about a major boost leak somewhere in my intercooler piping am i correct ?

if you want , i have a small video with sound to let your hear the car.

thx again in advance for you great help

you either have a boost leak or, if you are trying to run more than about 9lbs of boost its gonna hit boost limit, and you are feel like you are ridding a bull that wants you off you are gonna want to up that if you plan on running .9 bar

boost leak. pressure check the system.

if your max rev is about 4k and you can't rev and it cuts off it's definatly a leak in the systembest way2 boost gauges wll tell you that at all timethe boost at the turbo and manifoldtry it and you will see

i pressured my piping.. i got a slow leak around the throttle body AAC and air regulator .. i will need to dismantle everything and do some new gasket ...

its very slow ... well i take the time to go to my boost gauge and the needle is slowly going down.. is this enough to make my engine not boosting and just bakcfire and stumble?

Yeah boost leak is one thing, you also might have a vacume leek or one of you coil packs is bad. Does your engine shake a little while this is happening.
