You may want to check everything make sure its not off a tooth or leaking boost or anything. This is my dyno pull lh2.4 no chips +3 ignition mod with stock downpipe, ebay ic, and 2.5 side exhaust. 15g on 16lbs. So no chips or cam but I made more power still blowing black smoke Cause it was so dang rich. That was done with a blown head gasket
