2000 TTQ , apr 93 oct chip.. since installed, boost hesitation, and stalling on every first start in the morning. Someone mentioned n75 valve helped with stalling. No time to take it to the shop where i got it installed (they're open m-f 9-5, exactly the same time i'm at work) so i'm gonna try some things on my own. Any other sugestions are welcome.
Thanks

It's wide open at idle, so should not impact your issue. Could be a bad temp sensor ($5, or for an early 2000, a bit more).

is temp sensor easy to install?

Steve, what i hear when driving is a clank, clank noise, like it wants to boost, then the boost will finally go though if i push it. Not sure where the noise if from, sounds like a valve though,(this happends sporatically, sometimes its fine) i first thought the dv, i have a forge, took it out cleaned it.. no difference. any other things i should check?

Hope it's not spark knock. Your description sounds like a sticky DV on the boost issue...What's in the car?

TTschwing

5 minutes..

BoschTT

maybe i'll pick up another one. any better dv's than the forge?

and its just happens when the engine is 'cold' boost would 'jerk' the car

so what temp sensor are we talking about
