Idle issue post-tune

[WickedSS2005]

I recently tuned a friends '06 ss/sc for a 2.9 pulley with the stage 2 injectors (42.5#). I started with the same tune I've used on two other vehicles and began tweaking it to suit his car. About a week later he starts to get a choppy idle and it has died a couple times. I'm meeting back up with him this friday to re-tune, but does anyone have any ideas? I'll attach the tune and try to get a log of it this friday if it's still persistent.

If its choppy and dies sometimes, maybe the overall graph isnt smooth, try make it smoother, and it dies because it runs too rich..

Im just a beginning tuner, i might not be correct.. just telling you this because its what i would do to my car if it does that..

Overly rich isn't an issue tho, I'm gonna scan him again this evening to see what's up
