turbo lag
 

well i have a 7mgte and it seems like when the car gets hot or i push the car very hard, its start to lag. the turbo wont spool until 3500-4000 rpm. at the same time the car seems to backfire alot. i thinking its a leak but any one can give me a hint were this leak can be. oh yea also when the turbo lags, it wont give me the full potential boost.
