What is a good A/R on Decel I was driving through the Angeles Crest highway this morning and I noticed while coasting my A/R was mid to low 14's, shouldn't coast be 14.7 to a little leaner? On the same trip but heading down hill I noticed that while in gear on decel my A/R was like 13.5 and stayed there, untill I gave it a little gas and then went to 14.7. Shouldn't that have been at least 14.7? Just wondering if my tuner only tuned acceleration. My gas mileage is pretty bad.

Does DFCO ever turn on when you're slowing down? If not, I'd be trying to find out why not and then fix it. DFCO basically cuts the injectors and drops timing to less than 10 degrees. If you have a WB installed, it should peg lean during this as well.
