Dealer Flashed Over SCT Program, HELP!

[towerace81]

I work on my uncles 04 f-350 King Ranch PSD when he needs it. Mostly non dealer stuff, 5" MBRP turbo back with cat delete, Volant Ram Air intake, Superchips Flashpaq and so on. My uncle is not very savy when it comes to vehicles, but he decided to de-tune the truck back to stock with the SCT so he could take the truck to the thieves at the dealership to have 60,000 mile service done. he only thought he de-programed it, but actually left performance mode installed. long story short, the dealership flashed over the SCT performance program, now truck misses, smokes, lots of lag, no power! Help, what can be done to resolve this problem?

If the dealer flashed correctly it should have overwritten everything the SCT put on so it shouldn't be an issue. Sounds to me like they screwed up the reflash. Have you tried disconnecting the battery and resetting everything?

[towerace81]

yep, had bats out yesterday for about 8hrs while i was going threw EGR to see if that was part of the problem.

take the performance tune out. Does SCT also stand for superchips flashpaq or is he using an xcal?

[towerace81]

I removed the performance tune, changing it back to stock. The truck runs even worse now, shifting is eratic, sometime very stiff, othertimes it feels like its slipping. Truck has a very noticable misfire just off idle through about 60% throttle after it gets to opp temp.

Take it back to dealer for another flash . the program didn't work the first time.

Take it back to the dealer that flashed it and tell them they screwed something up.

ORRRR take it to a different dealer that actually knows how to flash the computers instead of going back to the one that screwed your rig up the first time.

My thoughts on this. Is why pay twice for the same job? Yes they messed it up and should make good on it. If they can't fix it the second time request refund and take it to other dealer.

[doubledee715]

who said anything about paying twice? Flashes are free under warranty.

Thought there was a $100 deductible on engine work. When over 36K

Yes they do charge $100 for warranty work that's done beyond the 3/36k warranty....

Trying to return it to "stock" with a saved OEM flash, after the dealer updated the truck with a newer flash, will really mess them up as you're then mixing-matching calibrations. I don't believe your saving the entire calibration to the SCT when your first save it.

Once the dealer updates your calibration level, that is your new baseline. You need new versions of your tunes as well.

Don't forget to unlock your SCT when you get the new flash in and working properly, and then save that to the SCT.

Thanks for all the input guys, I will get it reflashed and let everyone know how it goes.

You shouldn't have to unlock it if you get a new strategy and need new tunes. Although I am not sure if you are using an xcal or the superchips flashpaq sinnce you didn't answer my question..
