Glad you got it figured out.

Nah, you're not alone.

Yes, please post up your bin. Im still trying to figure mine out. :)

Edit- not sure i a leaking bpv would cause this because the air is pre throttlebody, either way. I'd check the iacv.

Well, as long as fuel pressure is good and injector size was entered correctly, id have to say that you have a boost leak.

Ebay coils. ~$75 for all 6.

And no other possible sources of air improperly entering the manifold? I know you checked the throttle linkage, but is there any chance of binding at the throttle plate shaft itself?

I don't think that boost is too far off the mark, though. Maybe a max of 16psi. But my understanding is that if you can squeeze ~12psi out of a stock setup, you should be able to bump it up about 25% when using 550 injectors. Have you tried the frequency clamp? Also, are you running in suck...

I used to have a problem with my floor mat, that when I went WOT, the pedal would get stuck under the front edge of the mat, and my car would bounce off redline. Dunno if that's a possibility in your case. Otherwise, I can't imagine the car being able to rev above 3000 without some sort of...

Ok, cool. As for setting mainscale to 20, makes no sense to me It tells the ecu that more air is flowing into the motor(higher frequency, closer to fuel cut point), and to step up fuel flow. When you install larger injectors, you do the opposite, and tell the car that less air is flow, so that...

Yup. And that vac nipple you see at the front of the intake is what connects to one end of that hard line in your pic. The other end goes into the idle-up valve on top of your PS pump.

I know that my fuel cut raised when I went to 560's. Did you set the proper injector size into the maft? (I assume that you did). You *can* set a frequency clamp, but I never had any luck with that.

Why is your mainscale set to 20 on factory injectors? What firmware version are you on? What DTC codes are displayed? Boost ctrl TPS start is set to 3.7V? Does your tps even get to 3.7V?

That would cause a visible external leak, though.

This is all good to know. I emailed Aeromotive, and they confirmed that the 340 Stealth pump does have a check valve. I suspect I might have a leaky injector or two. I guess I'll have to pull them at some point, and have them cleaned and tested. Regardless, I ordered a Fuel lab afpr with a...

What I normally do to start, is click over to engage the starter for about a 1/10 of a sec, and that engages the pump for 2 seconds, then I start normally.

I was wondering if anyone of you could share their experience with aftermarket fuel pressure regulators. The one I currently have is just Ebay crap, and I'd like to upgrade. I want one which holds some static(resting) pressure in the line, rather than draining down to zero after shutoff. Do...

See this thread- its got some good answers. http://www.supramania.com/forums/showthread.php?194325-Driftmotion-rebuild-service :rofl:

As quiet as I could make it with two performance mufflers and a new cat, but with a cutout. https://www.youtube.com/watch?v=IHv5Ve8Btr8

The front turn lights and the rear turn lights?? You mean front turn signals and rear tail lights? I think so.
