Well, if the intake temps were low enough, it might have been adding fuel, but driving around town, it was acting fairly normal, so I don't know. I'll be observing and noting things over time. I did start messing with the Accel pump function because it was herky-jerky if I tipped in too much, and I had often seen a lean reading in the beginning, but had trained myself not to stomp the gas, but rather roll on the pedal.

So, I added more fuel, tried it out, same thing, added some more, and after a few repeats of this process, I decided it was getting worse, so I took out a bunch of fuel, and things started improving, and eventually I got it so I can romp on the thing off boost in any gear and it just goes, no missing or whatever, then the turbo comes on and things start making loud noises. It's great and the car actually feels faster because of it. I guess it's because I can give the turbo maximum load so it probably spools faster/sooner, or I'm just delusional.

Anyway, it's all working out, but I have another question in regards to the accel fueling. What is a good AFR to shoot for upon tip-in? right now it usually goes into the 10's then evens out in the mid 11's like it does on boost. Should I take a bit more out and make it so tip in only goes to low or mid 11's or is it better to have a good, rich squirt of gas? The reason I ask is because if less fuel made it run good, maybe even less will make it run great?
