Have you givn it a good thrashing now u have the new pipe? cos it will boost higher, and quiker. also, check your vacuum lines, cos i had a prob like that, turned out it was a vacuum leak. it would idle up and down wether it was cold or hot. and sometimes stall at the traffic lights.

I had a problem similar to yours, in the worst case .....the car would have big trouble starting.

Ended up being the vaccum going from the little black box to the back of manifold was bristly and starting to tear (after adding a T peice), replaced the hose and all is fine.

By the way with a dump pipe should i notice more power gains, i have a full 3" system (inc frontpipe), and have a split dump coming this week.....i heard response is better, cant wait

depends on ur setup. a factory pipe will flow up to 250kw ish. bigger turbo, higher boost etc, and you will notice power losses. remember. flow=power=burnout.

if you changed your dump pipe, check the o2 sensor is correctly installed...

Can't hurt to reset the computer!

whats resetting the computer going to do?

make sure the bolts are all tightly done up, exhaust gaskets are in good condition, etc. An exhaust leak can cause unstable idle, possible stalling, etc.

resetting the computer allows the ecu to leanr a new power curve. generally if you have a stock computer you should reset it after every new upgrade

kryostaisis has a good point... after every mod u do, the engine will run and react differently, needing different timing and fuel requirements. resetting the ecu lets it "re learn" the motor to get the best out of it. if you get wat i mean...
