I had my tuner look at mine and he just had to go in and mess with the idle settings and something with the mass air was right and the the o2s were right and mine was fine I did bump the idle to 750 in my xcal and I rarely had the problem. If he would have dynoed it he would have been right on with it.

Its the tune. Take it to reputable tuner and he’ll work the bugs out. I went to three tuners before I found one that knew what he was doing.
