sure your timing didnt slip?

No i'm not sure but even if it DID slip, why would my turbo not whine half as loud, not "blow off" on shifting, and the truck wont go much over 1800rpms w/out sputtering real bad

That all could be low timing related, along with your bad MPG, and super easy starting.

Its funny you mentioned the super easy starting thing. Since putting in the starter and doing my mods, new fuel filter, and everythign in my sig it actually starts normal now. When it was in the 20's the other day the truck def took a second to start and I had to rest my foot on the throttle for it to start.
