Smoke help

What color is the smoke? Check for boost leaks yet? Check for codes yet? If you're on the 7m platform I'll bet you'll pull a code 34 if you do have a boost leak.
Get back with those two questions and we'll go from there....

smoke is whiteish blue but the car dont run hot and i was thinking of looking for boost leaks but im leaving for miami tonight so ill have to wat untill i come back i do know that the top intercooler pipe is to big its 3.5 inch and the bottom is only 2.5 inch
yeah thats what i said as well it was way too bigstarscream5000 said:Whoa there, get that changed out to a 2.5" also while you're at it.
well my other car has bad valve guide seals and it only smokes for a few minuts after it is started. i dont thing=k its the seals the motor only has 6k miles or so on it
well i blew off a intercooler pipe so that mean i had a somewhat of a boost leak but it still amokes so im changing out the turbo to see if that helps ( messed with the safc a little got rid of the gas smell
well swaped the turbo and that stopped the white smoke so it was the seals, but now if i get on it, it blows black smoke but only if i get on it... it also keeps wanting to blow off the ic pipes. i tried turning down the boost controller but the boost went from 10 psi to 15 psi and its only a stock turbo is the boost controller bad or something?
Try running straight off the wastegate. Sounds like it may be a little rich with the black smoke, but I'm not sure.
i have a safc II on the car, but i dont really know much about it i have 550's afm and fuel pressure regulator, but i am still hitting fuel cut i think.
