forced induction problems

IMO get rid of that chip and get a tuner. especially for your turbo setup, its worth it to have a Wide band o2 and a good tuner like tweecer or AFM PMS.

Not saying this is what it is, but i had a similar problem before. It ended up being the fuel pressure regulator went bad. seal must have broke inside forcing fuel into the vacuum line which feed it into the upper intake. when we popped off the intake gas came gushing out.

I also agree that your problems lie in the tune. I'm 99% certain of it.

I (as a noob TwEECer user) do NOT recommend the TwEECer unless you've got a friend nearby who's an avid tuner or a dyno shop with experience using the TwEECer.

I recommend you get a custom chip burned and be done with it.

If you wish to try and continue using that JMD then at the very LEAST, you should purchase a wideband o2 reader and RPM converter that is capable of data-logging. It would give JMD something to work with when you send them the chip back for a new tune. That's still crappy patch work though.

Custom tuning is where it's at.


Edit: One other thought. Are you using a blow-off or bypass valve? A blow-off can cause a temporary but significant fuel load-up on decell when metered air is being blasted out of the induction tract.
