Message	Basically i replaced nearly everything under the hood, rebuilt the engine and factory turbos (z1 w/ new chra's). Engine has wiseco's, eagles, rebuilt heads (original lifters re-used). Here is the problem, after dyno tuning with a very reputable tuner everything seemed perfect, a/f etc. Made my expected 360ish whp. After 500 miles I have equal amounts of smoke out both exhausts on accel, rev and decel. Engine still runs fine, pulls pretty hard etc. There is a slight lifter type tick which goes away after its warm, but i think that's from the original lifters. I have 2.5 dp, tp, exhaust, no cats all the way back. 16psi. It definitely has a burning and rich smell to it. I am going to have compression checked, but what else should I expect to do or have to deal with here?
