Hi, I'm no tuner but have been working on this and it runs pretty good. I know my fuel map has intersections and I know that's a problem that's why I uploaded my map for you guys to check out. I don't know anything about the ignition map either which is copied from a very similar build. One issue I continue to have is when I barely crack the throttle it will lean out hard (bangs and pops sometimes) usually worse if im just cracking(<5% tps) into 4th or 5th gear especially at higher rpms(usually recovers after about 3 seconds or so). I've heard it may be timing related. Thanks for checking out my tune.

Your tip in trim is -10% under "Fuel trim". Zero that out, or add a few percent above 0
