hi guys
i have a jspec tt which is bpu . fmic / boost controler / fuel pump / fuel cut off / everything i think.
my problem is when i floor it, the exhaust becomes very very loud , not the normal sound when you floor it , its really loud .
car is boosting as it should , but i feel i am loosing power when this happens.
i have no leeks on my nur spec exhaust.
after a while it returns to normal. nice sound as it should be.
i am no expert. but could this be something to do with my waisgate. also i have a stock bov, is that the problem?
thanks for the replys in advance.
