Re: cummins mileage true?
I had an '03 CCSB Cummins 6sp 4x4
4.10s & 35s. I got a consistent 18. My '94 Cummins 4x4
auto w 4.10s and dually got 17.
No offense to Iron but I just don't believe the low - mid 20s in a 4x4
. Maybe a 2wd with 3.55 gears.
'97 SCLB 4x4, 3.55, D60 w/ TrueTrac, 6637, Banks Techni-cooler, BTS Trans, Tru-Cool 4921 Trans Cooler, 1.0 exhaust housing, no ebv, 3" DP, Straight Exhaust, E-Fuel, TW tunes, International WP, 203*, Isspro Gauges
