Looks like it ran pretty well for a cold track. Looks like the tune could use a little tweaking and you are going to need a bigger HPFP to it seems. Do you have the stock fuel bowl still, airdog fass?

Looks and sounds good though.

Weren't you having issues maintaining rail pressure a year or so ago with bigger tunes? I think I remember you sending me logs and what not because your truck was not pulling well throughout the 1/4. Just curious if you ever got that issue addressed or not.

Yeah the bigger tunes were dropping rail pressure even on my stockers, just not as bad. Now with this turbo its even lower.

Eric, Im still running a stock lift pump for now. I have a Fass waiting to install, just don't have the upgraded lines and fittings i need. should have dyno numbers tomorrow.

That's odd. I would figure if it were a pump issue the pump would have given out by now.

Who knows, Could have been the Lpfp the whole time. I've heard it make some weird noises out of random.

The fass should help and even more so if ran direct to the HPFP.

That's the plan. Hoping to get a little more fuel with it. If not I'll just have to wait until I can afford a fuel build

Did you make it to the track again today?

Just curious but why is it dropping rail pressure more now with the single than with the stockers? Tuning?

Probably getting paid at work to post this from my D1

No, we decided to go another weekend.

Im guessing because my tuning is giving it all the fuel I have and the turbos cleaning it up. Not too sure.

Hit the dyno yesterday. Best numbers were 598hp @ 1079trq I'll post the chart later.

What was rail pressure on the dyno pull? Good numbers btw.

Super08Duty · Nov 6, 2011

Honestly didn't even plug up the DD for the dyno today. Keeps slipping my mind. some of the guys were saying it was completely clean when the turbo spooled then when i let off it would shoot a good amount of soot out.
