I e-mailed Allen about my LT's and which way to go if I was running lean, I had positive LT's (+1.56 & +.78) at WOT which I was told was lean and the ECM was adding fuel to compensate. I increased the PE +2% and rechecked them driving to work today. The LT's were running .-78% to -2.56% just cruising and finally went to 0.00% at WOT. That's pretty good isn't it? I had been running +3% on the Spark and have never seen any KR so instead of bumping it a little at a time and rechecking I decided to take a different approach. I maxed the spark out to +10% and checked it also driving to work, never saw any KR while cruising or giving it a little throttle, then I punched it to see what would happen, no KR at WOT either. So I think I might finally have a little better tune, got my LT's in the negative while cruising and zero at WOT and no KR with the spark maxed out. Hope it works but I'l keep chekcing it to make sure.
