This is an LQ4 in a tube chassis rock crawler running an th400. The tune that's in the truck is set to manual for the transmission. The problem we have is it has terribly slow throttle response when you need fast throttle opening. I was playing around with it today and changed the trans type to non electronic auto and wham, it has excellent response but won't idle no matter what I change. Even the scanner is unable to raise the idle. I can hold it with my foot and it stays consistent though. As soon as I change it back to manual transmission it idles fine and has slow throttle response.
Please help me

When I opened your tune file to check... oh, wait a minute. You didn't attach a file for anyone to look at.
