car problem?

[patsdsm]

a week ago my car started this thing when i get on it. It boost fine in first but from then on everytime i shift the car looses boost or power and falls on it face then the turbo will spool up again its weird it feels like the turbo isnt holding boost between shifts because as soon as i go into the next gear it takes a few seconds to get boosted up again please help thanks. sorry if i gave a bad discription but to make it easy the car pulls until i go to switch gears then it takes a few seconds for the car to build to go again

I had a similar problem i would lose power when i got on it and the car would want to stumble and stall mine was a loose upper intercooler house. listen for excessive air escape i didn't cath it cause i thought it was the intake or turbo sucking in air ..good luck if worse comes to worse go to the dealership to find the problem because they don't BS you just over charge. good luck

if i understand you correctly, our cars are supposed to do that. anytime you get off the gas (to shift or brake or just decellerate) the BOV releases the pressure still in the intercooler piping before the throttle plate.

Assuming you profile is updated, I suspect it might have something to do with fpr overrun as you are running the 255 with stock fpr. Also make sure that you're not venting as it will also cause similar effects.

How much boost are you running with the EVO3?
