Need help tuning 12V

JeepinOverU · 03-05-2008, 07:29 PM

Trying to tune my 12V today. My problem is right when I get to 6psi or so of boost it lets out way too much smoke, even if im accelerating normally. The rest of the time fueling is ok. What adjustment can I make to it?

an intake would cut down the amount of smoke.

First thing you want to cheak is your air filter and clean the housing, cheak your turbo and see that it spins freely. Unless you know someone who is a diesel Mechanic call around to radiator shops and diesel shops and get a price to test your air to air core, they test for leaks. Then do a valve set. That should keep you busy for a while. PLAY SAFE!

Tighten up the star wheel on the aneroid a bit if u want more boost before the fule comes on.

Thanks, I will try the starwheel I just wanted to make sure that was it just because it was happening after 6psi or so.

You knew you were going to get smoke when you gutted the afc. Right. Did you cut the foot down or off? If so the starwheel will not do anything for you. Sounds like you will have to pull back some on the plate?
