Is there any way possible someone from spartan could write me a custom tune so when I use my tow haul button it locks the truck out of overdrive for good? I regularly tow a 40 ft two car hauler weighing 17,000.... Pulls it great with the 175 file..... I've tried the 75, 125, 150, 210, 210 tow, etc. It just runs the best on 175. Although the truck runs at 1100 degrees. If I kick the throttle down then backoff and kinda hold it in drive instead of OD I can see a 200 egt drop, and probably would get better mileage...... This is all on flat ground of course...... Do any of the spartan diesel techs on here know if this is possible? I'll pay you to do it
Thanks Rudy.... I have to get something done before march 19th............ Junkass automatics. I wish I never would have traded my 04 6.0L six speed in
