I have never had any issues with 409 or 602.
I use a 202 file for my high idle and works perfect
Do you have a copy of the stock tune file that you can share?
Think he meant 602 not 202.
I was using a 202 that was posted of the forum. There was something wrong with that stock tune file the truck would not shift at full throttle. I using the 202 file for the tune depot. It was well but no high idle.
My bad 1st i heard of 202 .
