it shouldnt smoke that much, even for LB7, my LBZ will make a very faint puff if i nail it off the bottom, how much is it actually smoking?

Some LB7s smoke like that when you nail it, especially if the trans hasnt downshifted yet and you slightly bog the motor.

well from my experience, i followed my gf's dad on a 1200km trip and he was hauling a camper, and has a diablosport predator and he would only smoke a, little when he was chugging up a hill.... it didnt smoke too much...

Mine always had a little puff @ take-off, now it's a little more with the stock tune. I'm thinking it has to do with the 315's and the fact that I haven't run the stock tune in over two years.

My trucks does the exact same thing every once in a while when I floor it. Mostly going up a hill. My guess it its just the normal diesel side effect. I've never had any problems in 50K miles so I believe its normal. :happymugs

You guys do know you're all describing "lugging" or "loading down" the engine, dont you? :)
Diesels will smoke some when you lug them. IMO, its normal.

Warrenty is supposed to pay for all four. Submit the bill of the four you payed for to GM and they should pay you back. Last I checked, GM had not changed this policy.
