I picked up a used U7186 and tried it on my totally stock 2006 LLY tonight. No matter what tune I try to put in the truck it causes the truck to go into a limp mode. Pressing down on the accelerator does nothing. The truck will idle and that's about it. I tried 2 different tunes and got the same results so I ended up putting the stock tune back in.

What's up with that?

Mike,
Thanks for your time on the phone today. You were exactly right. Taking the revision from v9r02 to v9r12 fixed my issue. The truck is running great. I went ahead and put the 65 HP tune in it. Any issues towing with this tune or should I back down to the 40 HP tune for towing/hauling?

Good to hear.

The 65 tune is good to about 8000 pounds, any more than that, you should run the tow tune.
