So I was reading something the other day that stated if you have the dealer turn on the high idle program on a STOCK tune, that when you pull the base file from the truck and use it to write EFI tunes that the high idle will still be enabled once the EFI tunes are installed in the truck.
Is this true?
If so, or if no one has tried it, I think I might just take the plunge and have the dealer wipe my truck and turn on the high idle feature with a brand new stock tune to boot. I know HPT has this option for the 03-05 trucks and that kind of makes me envious.
If anyone can confirm this, maybe we could even just find someone who has a base file with the high idle enabled. But I guess there are several versions of the ECM software and we would have to have one of each for everyone to have access.
My truck is an 07 5.9 BTW.
Been snooping around here for a while, so I thought I would join and post up this *possible* idea of mine.
