need help..hesitation

[NBBacon]

ok, so when my msp is cold (within first few minutes of start-up), it pulls like crazy, all kinds of power. it feels like i'm getting all 175hp. after it warms up, if i step on it, it hesitates like crazy, is REALLY sluggish, and just feels like crap. and if i'm on the highway cruising along, and come to a little hill, the car won't just pull up the hill if i put a little more throttle into it, it'll hesitate and shake a little as i go up the hill......what gives?

the car is stock with 39000kms on it

do your rpms dip like crazy on their own? i would check for vacuum leaks as a precaution. also flashed or not?

I remember someone here having a similar issue. Their problem ended up being a crack in one of the Intercooler pipes. The crack would open up as the pipes would soften from plastic pipes heating up.

Your problem definatly sounds boost leak'ish.

do you have a boost gauge to moniter the boost?

if so then we can be sure how good of a guess we got.

good luck!
