My starwheel is all the way forward, my afc is ff as well, and so is the fuel plate, so pretty much everything is full forward and I'm losing my smoke after 6psi

Your losing fuel pressure.

x2 on fuel pressure theres no way u shouldnt see big results with the right plate and everything forward.

When was your last fuel filter change? Did you clean the strainer? Simple places to start. :pca1:

ALRIGHT I took the plate out now to see if I got more of a gain, trying to eliminate what could be wrong.
I am burning coal now under 6 psi(I'm going to adjust that smoke screw more now), my boost is way better now. Instead of hitting 30psi at 2300rpm, I was passing 30psi going to 40psi at 2000rpm, I had to let off the throttle obviously as I saw the gauge still climbing.
I'm going to make a boost controller tonight to hold my boost at 33ish.
Since the truck performed way better with the plate out compared to with the #11 ff, does that eliminate the fuel pressure possibility?
My fuel filter is new along with a new lifter pump

Imho, your fuel pressure is fine. I would still clean the prefilter screen or get a new one from cummins for like $8, dont go to dodge and get one, I think they want around $44 for one. Just keep a eye on the egts. The first time I pulled the plate I had stock sticks and stock timing and hit 1400* pretty easy.

You have revealed the issue, now to see how many people can tell you the cause.

joco12v 11-15-2010 10:15 PM

Surprisingly I still only got my egt's up to 1000, maybe because I was letting off the throttle once it tried going beyond 30psi
