Mileage for the first 2 days after engine conversion and SCT Tunes
 

I've spent most of the last 2 days on the performance setting with a new 4" turbo back exhaust so you can imagine how many times the pedals been mashed.

I pulled into the gas station at a smooth 3.52 a gallon for diesel :notallthere:

and only put in 11 gallons! I did the math and I averaged 15.4, I realize that isn't exactly gonna win a prize for "being green" for the environment, but I can't hardly be dissappointed. This truck was getting 12-13 ish at best with the old 03 engine in it and babying it. I have a crappy strategy (VXAP2N2) and this is not terrible. I'm not sure if would do it all that much good to get a roll back done by PHP..... OR WOULD IT??? please share your stories

The truck is a F350 dually with 4.10 gears.... :hmmm:

.....I take that as a no :cheesy smile:

I'll share as soon as I start making mods. I can tell you my '03 7.3 could get 16.5 mpg with bald tires but I can't get better than 13 with the new ones. :sigh:

BTW.... my conversion is an 06 engine in a 03 truck...... I noticed I didn't put any info down.

Anybody?

buy a gryphon
 

trust me just order a new gryphon then you own it and pay bill 4 the programming it would be the quickest


an 04 original rollback ??? this will depend on your build date and the sticker number on your pcm

ficm = AMZ2AL09.PHF

trans = TQBD1N6.PHF <--- includes the original tow haul that came factory>

pcm = VXBC1NZ.PHF <--- includes pilot injection as came with factory>

all these files can be downloaded at DSFM File Download

but bill has them on his server and runs your computer with remote desktop and programs the gryphon in different modes to program your trucks different modules
