Re: Lopping at idle
I wasn't closing it, I opened it more. The TPS and IAC was unplugged when I made the adjustment the truck was just under desired RPM at idle, about 700 RPM then I turned the engine off and plugged everything back in and tired to start the truck and would not do anything but crank. It was turning over like I had the pedal to the floor. That's never happened before until I loaded the last tune in it.

Well that obviously has nothing to do with the tps.
You obviously need more crank pw when hot.
Go kick up the crank pw at operating temp by 35%

Re: Lopping at idle
Should I have erased KAM memory before I loaded the last tune you sent me ? or dose that really matter.

Shouldn't matter but can't hurt.
