Default Help Me Out

Hey guys, i posted a while back that mainly in second gear when i full throttle the car it jerks and i can hear a sound almost like blow off valves... i was told to do the Vag Com which i did and when i posted up the codes it was something like over boost... i really didn't receive much help on what it was and when i searched on the forums i didn't really get any other answers then disconnect my ecu. I believed originally that it was my MAF which i got check out and it was not. My question is has anyone had this problem? Could Vag Com not have picked up the issue if it is a hose leak or BPV leak?

Default haha, sounds very familiar,, followed w/ a cel w/ me though, checking the codes soon though..

soor i cant help you more, as people have been telling me, maybe a boost leak causing overboost..
block 115 i think is your psi of boost w/ rpm's and thatll show if your boosting too much as a result of a boost leak

Default Have you pressure checked the car yet? With the symptoms that you have it sounds like a boost leak

could be causing the noise that you are hearing. The jerking could be TC (throttle cut.

Boost leaks can cause overboost too.

Default I had this prob with a fault in my EGT sensor combo w/ 91 on a 93 oct chip.

I fixed the egt. prob still is MINIMAL with the lack of 93. Hoora for Utah!

Default i'm gonna bet you have a boost leak, have you checked the throttle body boot?

very common problem, you need to pull it off to check it properly..i'm willing to bet its a boost leak.

no i have not pressure checked my car.... Is this something you can do by yourself, or do you need a place to do it? If so how do you do it?
