OK, here is the deal, I have a 99 z28, front mount turbo . I cannot get more than 2 psi of boost. I upgraded my turbo, added an intercooler, and replaced my wastegate. Nothing.

. I do not see any leaks in my charge pipes. Blowoff releases slightly when I shift. I grasphing for straws here....Is it possible that my drain line can be slow to drain ( because it only has a very slight slope to the oil pan) and causing my turbo to "choke" on the oil. Not allowing the blades to spin freely

. Only blows smoke at wide open throttle at high rpm about the same time I hit 2 psi. Any suggestion will be appreciated

Thanks
