    Cold start idle - 220* Please check...

    Well, after reading over the post of "What to do first" I modified my .cfg file and re-logged.

    The car likes to stumble and fall flat on its face on a real cold startup. This morning was a bit warmer than usual, and it didnt act up as bad.. I will re-log again when it is much colder. My LTIT's look way off and the STIT's went from way positive to way negative. Very odd. If someone can lend some advice, I would appreciate it. The cam in the car is big. 238/242... 42# injectors, LS6 intake, BBK big tb, QTP LT's, no cats, 3" magnaflow exhaust.

    Here is a copy of my tune, log and the .cfg files.. Thank you for your advice.

    The first thing I would do is adjust the TPS. You are at .63 volts. The spec is .45-.55v

    When you are out of this range you move to a different fueling cell and you can have idle issue.
