MyTurbo, I went round and round when I had the issue. First Simon at Motec said it sound's like the cams. I didn't believe it since I was sure I had them right so I completely replumbed the fuel system on the engine. There was no change. Then my tuner said it sounds like the cams. I didn't believe and thought it could be some other fueling issue so I tried adding more fuel to one side and taking fuel from the other with ECU programming. There was very little change.

So I pulled the engine and checked the cams. Sure enough they were off, probably more than I'd like to admit.

At least try to pull a plug from each side and see what they look like. All 6 left plugs looked almost identical and all 6 right did too, they just looked like they came from different engines.

BTW, the build looks awesome!!!!
