RE: Are you a Big-Rig Hypermiler ?...
Hi All,

I have an isx15 2350 engine. I'm not sure what's going on with the acceleration from 9th to 10th gear. 9th gear won't climb past 1500 rpm and change to 10th gear it falls back to 110p - 1200 rpm and lugs the shi#t out of the engine before getting back over 1450 rpm. I have Cummins insite is there a vid or does someone know how to change the parameters so 9th can climb over 1500 rpm before shutting off, and accelerate quicker in 10th with less speed? 10th gear is only 1500 at 70-75 mph and and 13 at 65. I'd like to be at 65 max speed but 1500 rpm. Hope this makes sense and any help would be most obliged.
