Hey guys so I'm running pretty rich and having issues idling/stalling. I just recently purchased a pte 63 mm turbo and I'm running a 3 bar/60lb seimens/snow performance with a turbo tweak tune. My question is whats the fuel pressure supposed to be set at during idle with vacuum and without. Also i keep stalling and it wont stay running only does if i turn in the idle adjustment screw it helps the car stay running decent and doesn't bog/sound like a diesel as bad, car sounds like its missing and the rpm's do fluctuate a few hairs.

Re: 2 Issues Fuel pressure question/stalling
Fuel pressure should start at 43psi line off. It will drop 5psi or more when you put the line back on.
What is your air/fuel ratio at idle?
What is the IAC reading at idle, warmed up, in park?
What is the BLM reading at idle?

Re: 2 Issues Fuel pressure question/stalling
My air fuel is around 10 at idle and im at around 43 psi. As far as IAC and BLM ill have to get that in the morning. I'm not aloud to start my truck up at night anymore since i did the fender dump it kinda wakes everyone in the house up haha.

How far away is the end of the fender dump from the O2 sensor?

Hey Eric, Sorry I finally got a chance to get back online my laptop took a crap this week and now I can't install datamaster. But the end of the dump is 22 inches and from the downpipe flange it's about 11 inches. Also I seem to get it to stop bogging stalling found out my meth kit was turning on below boost pressure. As far as counts I'll try to get them this week I feel I have a defective wideband it was reading 17 no matter what fuel pressure changed and I wasn't getting the flashing knock engine light. It's funny it spits a few puffs of black smoke out pipe and still feels rich but I guess I have to wait to get the datamaster running to figure it out.
