    Default 98' LS1 IAC questions...

    So I have the tune pretty close now, but I am still having an issue with how the IAC reacts under low speed turning... i.e. parking, etc. The car is a 98 ls1 6 speed with a custom cam ( 227/228 .. 649/598 ) and all bolt ons. The car idles fine and is good in stop and go traffic, but everytime I turn the wheel at low speed , rolling or not under any power, the car idles down and just about dies everytime. What tables would I modify to adjust how the IAC reacts under low speed with no load? I am tuning with V1 with all the updates? Attached is my current tune...Thanks in advance for any advice
