I went from a nice chirp of the tires from MAF tune to taking off like a turd in SD tune. I've got the Fuel Trims dialed in and dialed in WOT "narrow band way" 880-890 on the O2 but it's slower then Christmas!!! The MAF tune was good but I wanted to dial it in and get it as close to perfect as possible before I can get a wideband. Is there something I am not doing on a SD Tune? Someone has to have insight.
