Car Idle is rough

[BigTady]

All, i've done some tuning and got the car running a ton better however it still idles rough and has some white smoke coming from the tailpipes. It's not too bad just a little but i see it float by as i'm at stoplights. Driving is nice and smooth and the car seems like it has plenty of power. I also think i have a exhaust leak from one of the new header gaskets as i can hear it tisk tisk over and over again almost to the point in thought it was a bad lifter.

Hope that's enough detail, any help on this would be greatly appreciated.

Here are scanmaster readings from last night if that helps:

O2 MINIVOLTS 042-054
RETARD DEGREES 0.0
AF 5
L8 35-43
BAT 13.3
INT 128
BL 142
MPH 00
CLT 160
ATS 118
r 750-850
TPS. 44
IAC 14 (20-25 while driving)
CC 204
MAL 00

Fuel is now set to 43.

If you have an exhaust leak, those numbers mean nothing. Fix that leak ASAFP then go from there.

Just got the new gaskets today, plan to hit that project shortly. Thanks for the feedback.
