Hey everyone I've addressed this problem here before and no one could help. But the other day i was driving i lauched from a stop the car pulled very nicely in 1st which it hasn't been doing lately then i reached around 6k and my power just dropped. The car was still on and everything but i went from full power to nothing even made me and my girlfriend lean foward from the power drop. Anyone have any idea why this happens? Also my car is kinda loud when i first start it How a exhaust leak or a crack in my DP cause this to happen?

 

you ran outta turbo. just no more boost.

 

or limp mode/overboost. 2 kind of limp mode, one long term until something is fixed/changed for sure, the other is a momentary thing where the car just isnt happy pushing as hard as you're trying to make it. I can make my car fall flat like that since I have a manual boost controller, and no chip/diode, by turning boost up past 18psi or so. Cant remember exactly where the cutoff is, I've had my controller turned down to 7psi since winter.

mods? boost controller, chip, diode?

 

OK.. But why would I lose Boost. All my hoses are new i take apart and clean my BOV/DV once a month making sure everything is tight... Why would this happen.?

 

still don't know what you've done to the car, so can't really answer that.

 

2000 Audi TT 180 FWd
Mods. Ebay DP, Cone Filter, Forge DV/BOV, Garrett Boost Gauge
Nothing Crazy, No Check or anything. My car also while driving if i let go on the gas then step on it the car shakes a little.

 

what does your boost spike at?

 

When theboost runs strong its at 10-11 psi. If I had a crack in my dp could that effect my boost/ performance ?

 

yup, depending on how big of a crack. Also the car should sound a little bit loud on a cold start. After about 30 seconds it will quiet down.

make sure all of your exhaust connections are tight as well.

 

it might be the cone. too much air flow and it could do what its been doing. mine does the same thing, but im about to get mine chipped and boost control it.
