OK.......... I have a Superchip Programmer, it came with the truck. I put the truck back in stock mode and had the high idle turned on at the dealer it worked fine while in stock mode. I put the tuner back on the truck and the high idle didn't work. Figuring that the tuner screwed something up and already paying $90 for the dealer I just gave up on the high idle.Fast forward to this winter. I decide to just go and have the dealer re turn the high idle on. I make an appointment for this morning and head to the dealer.The service manager comes back and gets me to show me the "flash" has already been done. I tell him yea I know it has, I had it done here. I also tell him that the High idle isn't working.The mechanic says he thinks that he can just flash it again and see if that works, but the service manager over rules him and says NO it may screw something up by re flashing it again and not to do it. He's not sure why it isn't working if the flash is already on the truck.I finally tell him look, you're the Dodge Dealer if you can't tell me why it's not working or what you're going to do to fix it just give me my keys and I'm outta here.

Ah, just go ahead and buy the fooler from Prowelder and try it. If it still doesn't work your still digging for the issue, but eventually you'll get it figured out and your going to end up geting the fooler anyway. I love mine

They are extremely useful to have!

Well, I ran up to the local station (2 mi) to fill the truck up last night. It was 23* I left the truck running and it high Idled while I was filling it up. It was nice to have a warmer ride home.Not sure about the brake switch, but I did check the NAPA site and it's only $11 if I need to change it out.I'm pretty sure all other conditions are being met.I'm going to monitor the auto starter / manual starting of the truck and see if it differs. This is the 3rd starter I've had put on by the same place, but the first diesel so it's possible that's a problem. But they are very knowledgeable and have been in business for many many years.Now that I know the high Idle is enabled for sure I just need to talk the wife into a "fooler" I'm telling her it would be sooooo much better when she's driving it when it's cold outside.

Just tell the wife that you would be helping yourself, her, and an American college student's business!!!! But in all seriousness, it sounds like it is okay, I'm just wondering why it isn't kicking when you start it up in the driveway... Wonder if it has something to do with that remote start. You might try going out and starting it the old fashion way and see what it does.

Or you could just let the wife start it each time since it worked for her. Not sure how she would like that but you never know until you try.
