    LS2 idle timing and AFR

    My car is idling from 10-13 degrees of timing and the afr is about 13.2. Is that a good number for an LS2? Seems to run kinda rough, but then again it does have a decent amount of cam for being stock.

    No, thats not good, its running rich at idle. You want to shoot for 14.6-14.7AFR. Timing needs vary, but I'm sure you could use more than that.
