My lb7 this morning started reving at start up. It only revs once when it fires at startup. Any ideas??
Any ideas??

Becareful man if the oil seal is bad enough on your turbo the truck could start running on the oil and you will have a run away on your hands.Happen to a guy with an lbz not long ago he was trying to rip out the wiring to stop it and he didn't get it stopped in time before it hurt the motor pretty bad.
That's my guess as well... If it was leaking oil there should be some signs out of the exhaust
I'm driving now I will try again when I stop. I believe it revs and immediately then idles normal. So if its the fpr is it on its way out? Is that a warning sign!!?? I'm not to keen on the turbo either iv had my doubts about this turbo for awhile now.
Just got home. Every time u start it. It will fire rev up then go back to normal on its own. Every time it has the same manner. Fire , rev then idle or fire rev, rev idle.
Sounds good. I think I have three laying around. I can't remember. R they all interchangeable or not? I know the plugs differ a bit but other than that r they the same?
If it comes straight out off the for its a lb7s lly if it 90s off the end its a lbz lmm other wise you tuning may need to be calibrated if you use a different 1
