Thanks - and a question?!

[Demo250]

Got everything installed about a week ago. The tunes are awesome! It's a whole 'nother animal now. Thanks PHP, great product with a great price!

Anyways, I just have one question - position 2 is high idle combined with a tow setting. The high idle is on a 5 second delay. It works great when I first start the truck and for about the next 5 minutes of casual driving it continues to work when I stop. But it seems like after the truck reaches a certain temperature it will never come on again? I sit and wait and wait and wait, and switch between tunes trying to get the high idle to come on, but it wont. I turn the truck off and restart it to see what happens, it still wont come on though. If I park for a few hours and the truck cools off it will work again when I go back out.

Is this supposed to be happening? I was under the impression the high idle would help with cooler AC or spinning the alternator quicker if I was running a winch or something... but the high idle becomes a dead feature after about 5 minutes of driving. Any ideas? Or is this tune just strictly a winter warm up feature?
