I guess i need to open my wallet again and buy some more tunes thefermanator 02-01-2010, 11:34 PM What does your stock tune get? Are you hand calculating or going off of the DIC? What size tires? Mike_S 02-01-2010, 11:49 PM Most of the timing gains to be had on an LB7 are in the timing tables. Do lots of reading and get really fammiliar with them. I have an LB7 truck runnin around making 525 HP and throwing down an average 19 MPG. romig 02-02-2010, 10:07 PM my stock tune gets 15 or so and yes its hand calulated my truck dont have a dic DIESELMAFIALB7 02-03-2010, 12:14 AM you wouldn't be talking bout me now would you mike? :) vortecfcar 02-03-2010, 06:52 AM Speedometer inconsistencies are the number one culprit I come across regarding high or low MPG numbers. If tire size was corrected on one tuner and not on another the MPG numbers will show off by the same percentage as the speedometer. Winter fuel and cold running also cost quite a bit in the mileage department. If these two variables have been sorted out, and you're sure it's not your heavy foot causing the trouble then by all means contact me personally. I'll see if there's anything I can do to help. :) Nick Pulpit 02-03-2010, 08:11 AM Nick has been more than helpful anytime I have been in touch with him regarding my truck. I would recommend him to anyone who needs Duramax Tuning.
