Appreciate the response. I did contact the tuner with what I was seeing. He sent a revision but didn't say what was changed and the problem appears to be fixed. It sounds like you're spot on though.if its dumping fuel just a bit after startup but not at startup and the fuel trims are good in closed loop then that means its jumping in to closed loop too soon while the hegos are still cold
you would go kick up the closed loop delay time. A necessity when dealing with long tubes or any exhaust modifications that push the o2's farther back making them take longer to warm up.
