Question Did the dealer detune my stock truck some more???

[JLDickmon]

There is a required driving period after a truck has been reflashed. This allows the PCM to set the parameters for your driving and local area. There is a new FICM reflash that helps prevent FICM issues, by your post seems like they did that as well.

Drive it like you normally would over the next few days or week. Hopefully there won't be any additional issues with the way it feels.

It's an adaptive memory.
Drive it like you stole it.

I had the reflash done last month when the truck threw a cel. right after that i towed our toyhauler and felt that it had less power on the uphills, but it did bring back the downhill engine brake control.
in town it still feels slow/sluggish
(truck is still stock) i'm starting to look for a tuner.....

Call Jody at DP Tuner and tell him John and Dennis from SDD.com told you to call.

DP-Tuner will reflash a hot tune into your PCM for about $75

I took your advice and she seems to be snaping back. Guess I was being to easy on it when I got it back from the shop. I huled 2000lbs of rock today for my dad and you could hardly tell it was back there. Except for the fact it rode like a cadillac. I have power off the line and keeps me planted back in the seat. Thanks for all the Info Guys.
