2008 6.4 Dually Extened Cab Long Box with Tow Boss and 4:30 gear ratio
Well I did the full delete yesterday. SCT Livewire 5015C, S&B CAI, Sinister inercooler pipe, diamond eye exhaust pipe.
The good...... this will be short. The guy's that did the work were great!
The bad........ Out of 10 custom tunes installed the only tune that works is the B4 or number 4 tune. The tuner came with zero paper work so I don't even know what the horsepower is on this tune but what I do know is I want a bit less! The truck turned into a SCAREY MONSTER! If I was into drag raceing I'd have some use for it. It would most certainly ad up some kills! I tried to de-tune the beast one step at a time, first down to tune B3 and after loading the tune I got a wrench "with no code" and the truck turned into a pooch! A total slug! So I thought I'd try the next tune down, B2. Well after multiple NO STARTS, and 2 hours
of trying to load B2 I simply gave up, for now! I then loaded B4 back on and did some more testing. The shifting isn't smooth like it was prior to the deletes so that needs work or learning , if it will ever learn??? One note: IT IS EXTREMELY DIFFICULT TO STAY OFF THE PEDAL WITH THE B4 TUNE....HOLY MONSTER BAT MAN.....
The little good that may have come out of this...........
My liar meter showed 15.6 MPG when I pulled into the shop. When I left I filled the tank and on a 159 mile trip home the liar meter was showing 25.6 MPG. I stopped and refilled the tank and on paper I'm getting 15.9 so the overhead is waaaaay off. The only other paper MPG I did was on a 2000 mile trip where I was getting high 10's. I think there is room for improvement in the MPG department and hope that "if" I get the lower tunes to work that perhaps B2 or B3 with a little less HP will save a little more on the fuel. My main purpose for the deletes other than letting this truck live longer by dumping the EGR and DPF is the MPG.
Anyone that has any 5015 C experiance, please share!
I'll update after Monday when we call in and beotch!
