I guess I should replace the temp sensor to be safe.

This adjusts boost onset and controls wastegate creep (The N75 duty cycle is such that a small amount of boost is passed to the wastegate, cracking it open a little) Since our turbos spool so quickly, you really don't need to help them spool any faster. 3/4 though will control the creep (faster reaction time by the turbo) without throwing you into a full boost scenario which hinders driveability...

That would be a start....

like one full turn? My new Dahlback chip seems to bring boost on quicker whereas my previous APR 93 oct didn't come on so fast. Dahlback recommends not having a boost machine on at all...but after putting in the chip, it felt like it needed it, so I put it back on and dialed down the regulator to a little less than 4 turns. would I also have to adjust the creep? is that possible?

Until you log the N75 duty cycle. One interesting thing we learned was that a stage 3 APR holds at 100% duty cycle (no wastegate opening air signal) well into the RPM range. Stock or my APR starts at 98% and begins to taper earlier (sending a signal to open the wastegate). I don't know how the Dahlback is programmed. When we threw a BM on Quicksilva's stage 3 we didn't have time to tune it so we went 3/4 on the Relief, 4 on the regulator and it was Perfect first try..

It shouldn't be opening up at boost, only at negative boost? Right Mr Schwing?

it would really hammer the valve shut, and the results were the same. I am getting a bad feed from some sensor that is not allowing me to build boost over a certain psi. I am beginning to feel more and more that it is emission related, this problem started after running a batch of race fuel.

revised! ;-)

Excellent!

nice. thx steve.
