The last couple of day the truck has been running weird.
As soon as i get on the pettle, and try and biuld a bit of boost the etgs go way out of control, and the turbos lag badly. I can only hit 25 maby 30 psi witch is half of what i was doing before and the etgs are at 1600+ ,and i didnt make any changes. Its blowing alot of back smoke, more then before, and maby abit of white smoke just before the black smoke.

Before i could hit 50 pounds, and not even break 1250d.
now it 25 - 30 pounds and 1600+.

Any thoughts?

Joel

I'm not any where near as into these trucks as you are, so if you've already checked what I can come up with, thats why.
Could one or more of your injectors have gone bad?, somehow have a clogged nozzle or something?
I'm sure you've checked but there's the possibility of boost leak.
Blown out intercooler?

If that's not it try some of those new platinum plus 4 spark plugs, I hear they make a lot of power. :lol:

maybe your injectors arent poppin off right just dumpin fuel in makin white smoke.... just a thought... see if your turbo spins freely then check your boost boots and tubes

Injectors were fine, but it doent mean they still are, i think the very ittle bit of white smoke is just my leaking top turbo, that i havnt got arount to fix.

I think its a boot to, i stil havent finnished the twins yet and theres just a patch job booting system in there now so it wouldnt suprize me if that was the answer,
Buts its amasing how a little boot issue can make such a difence

Either that or the I/C popped. Just whip up a tester and throw the pressure to it. You should be able to hear it leaking if you lost that much.
