Just looking for experiences/opinions. We are full-time RVers. Towing approx. 15k HitchHiker fifth wheel with a 2010 DRW Crew Cab long bed and 68RFE tranny, full deletes with a RaceMe Ultra tuner running box tunes (version RAME007C). Running the stock power tune.
My question is this: while towing, what would be the safest RT tune to use? Don’t want to toast the tranny. Don’t feel the need for power, just looking to improve fuel economy where I can. Also, when selecting the RT parameters, what about rail pressure, timing, and torque? Currently, all those are set to default.
Thanks in advance,
