2015 cab and chassis slowest fuel guzzler ever?

blcsmok · Jan 10, 2015

Does anyone have tunes out for these? I found some for the super duty but they won't program into a cab and chassis. It's a new work truck, was sold on the big 420 some ought horsepower from the dealer come to find out the cab and chassis is detuned to 300hp along with some other minor differences. I don't want to hack the truck up. Preferably keep the egr and dpf for smog but 7.5 miles to the gallon isnt cutting it.

We could probably do a custom tune on the sct depending on if we can get the base file loaded into advantage.

I tried the edge and the sct neither wanted to

Actual edge and sct corporate? Of course they won't. It's all got to be custom tuning.

I wonder if this has anything to do with the number of c&c turbo failures on previous year models?

Huge thanks to Dyno Proven! Took it in yesterday and Cassy got it running right with her tunes :] It's a complete different truck waaaaaaany more power , I kept the EGR and DPF for now. Feels alot better not to have everyone running you over all day. I'll post some mileage soon!
