Just wondering if you guys set your tune back to stock before you take the truck in for service or if you just tell the dealer not to flash the pcm. thanks

 

I guess if your just going for an oil change or somethinglike that I would not worry about it but for other services I would put the stock one in

 

The only time I returned this truck to stock was for the 06 recall for the instrument cluster recalibration for the ABS light issue. Didn't want to chance it, even though they said it was not a pcm reflash. Did inspection, all oil changes and tire mount/balance/road force with tune installed. It depends on what you take it in for and if your dealer is ok with it. You may not want to fess up yet if you have a new truck and many miles left on your warranty ..

 

Although I don't have a tuner, yet. I would return to factory settings anytime you go in for service. Dealer's are known for reflashing without prior authorization. I think there are some flashes that are mandatory updates, but not sure if that's totally true or not. But the point is, go in with factory settings. Just check paperwork and under hood for evidence of a new flash prior to loading your tune

 

Thanks for the answers. one other quick question. how long do you run the stock tune before bringing it in? thanks

 

I ran my truck for a week or so, so that it could relearn my driving after the return to stock.

I forgot once when I dropped it off for an oil change but it didn't matter
