LTFTs -4 and +4 = 0 Basically perfect! Short term will bounce around based on idle, running, and WOT conditions. If short term stay between -/+10, it's good. You might have a little carbon build up. Drive it like you stole it! Blow out carbon out the exhaust! Driving it like a BMW M4 eventually stopped it from smoking. I6 like RPMs! I better start planning on a fuel pump replacement soon. Maybe after it passes inspection this year.
