My truck has about 104000 mile on it and this morning I notice a large increase in power delivery. Not sure if I should be worried about this sudden change, or just be happy about it. Is it possible the fuel preasure regulator is going bad? By the way the truck has no fuel managment devices connected.

Is it blowing black smoke out of the pipe, which would indicate excess fuel. Also fill out your signature and tell us what kind of truck you have. Look at my sig

I live in central Colorado, and the air temp has been around 20 deg. for the last few weeks. By the way I have an 03 LB7 w/ Allison.

I dont know that there is an issue with the sense of increased power. One for sure way to tell is if there is more black smoke coming out of the pipe. But if the smoke is at stock levels (almost none), then she must just be runnin like never before!

OK. Maybe is the cold dense air then.

Just so ya know, under User CP you can go and update your signature so you dont have to tell people reading your posts with questions what year truck or what you have done to it etc etc :D

This worries me!!!!! Has anyone heard of a wastegate failure resulting in excessive pressure build?

Maybe it would help if I described the amount of extra power. Burned the tires through a 6 lane intersection, transmision shifted up through 3 gear. It has never done that before!

My truck is blowing excess black smoke and is hitting higher boost levels than ever before. It also takes longer to start.

I figured out the problem. The differnce lies in the transmision TC. Lock up is happening sooner. The learn mode was reactivated earlier this month.

I don't know how that would affect it that much? 1st gear still only has the amount of torqe applied to it by the engine? Those with much more knowledge then me may respond but my stock 03 has never smoked the tires across 6 lanes... come to think of it I have never smoked the tires,, actually, I never tried. To much $$ tied up in it. :D
