I?ve got an old 4 1/2 Cummins Dun manual swaps stuck in limp mode looking for a stock or juiced manual tune or somebody to help go through my existing tune

Do you want to just post the current tune on the truck and read the codes to see what's causing the limp mode?

Here is what iv got in the truck now iv had a few ppl tell me they think the file is bad but i honestly don't know what i do know is that i cant brake the tiers lose in my gravel drive way the truck ran grate before i did the trans swap other than it the auto that was in it slipping like crazy now has absolutely no power no haze between gears or in a lug i bought the truck with a bullydog tuner in it and it was working just fine before i did the swap now after its useless
the truck is bone stock other than the air dog pump and 5inch from the turbo back
as far as codes go its not showing any active it was popping all the trans codes until i turned them off in the DTC dop
It's a stock tune with CP3 in Override Mode and a few limits moved for Turbo and Torque Limits. Hope you didn't pay anyone for that.Originally Posted by Mrhooker
If there aren't any boost leaks, it'll just drive like a standard truck.
Happy to take care of you for tuning, but you should connect your VCM Scanner and read the DTCs.
I'd suspect one of them is CP3 Overpressure.

mind ya i start out in 2end and shift point you can see off the tps
it just got nothing on bottom side of the rpm range of no lug so to speek on 3 and 4th and 5th is just doging out
