Having Trouble. Please give advice

[ntrimm]

I installed AR Headers with cats, CAI, 160 t-stat on my 2008 LS3 A6 Corvette. With the stock calibration/tune the car Idle's rough when the car is in drive and at a complete stop. WHen the car is in park or neutral it is fine. When we changed the calibration/tune, I had my tuner change the Idle RPM only as I suspected it was idling too low which was at 500 RPM Stock. He changed it to 650 and now it idles perfectly. I have checked all exhaust and intake to ensure no leaks. I have checked o2 sensors to ensure they are not crossed. They are fine. I have checked MAF to make sure it is installed correctly and it is. When we installed the headers, we checked everything to make sure there was nothing touching underneath the car. I am at a loss for the answer to this. Any suggestions would be great.


Thanks

do you have a log/tune file that someone could look at that would help in pinpointing the problem in the tune/log

hopefully joecar see's this thread he's a wealth of information

Might need some more airflow in drive due to the load from the trans or timing etc.
As above, post up a log.
