I can understand the desire for better shift points when using cruise control, or anytime for that matter when in hilly or steep terrain. I can control my own shift points pretty good with the gas pedal and no cruise. The biggest downfall of the gas engine is going down a 6% or better grade. With my diesel the engine braking would hold me back to a desired speed, with this V10 in tow/haul I still have to push a little brake once and awhile to take some speed off. I suppose the 5-Star Tune could help that a little but I am fine without it. I know to stay off the brakes enough so they don't overheat.
Being a part time RVer the performance of the V10 just isn't a huge priority to me. I will spend money on suspension upgrades to make my rolling turd handle better but it runs "okay" for me right now.
