I have an LS Vtec with built bottom end(toga bearings, eagle rods, srp pistons) and full skunk2 valvetrain with stage 2 cams. The car idles great and revs smooth, but when actually driving, I have no power. It kinda accelerates at its own pace. Is this a timing issue? I just recently put it back together and adjusted the valves, but I am not totally sure I have the timing right. Someone please help. Also it is in a 90 hatch with a Zdyne ECU.
