Hello, I have a 2014 Bounder and was considering the 5 Star tuning. While I understand many will have different opinions, I don't expect any material fuel efficiency, rather I was hoping for better shifting especially up hill. I also watched a video online that tested the 5 Star tuning and it was done with vehicle in "tow mode" without an active tow. Would this change the 5 Star tuning function? Would I benefit having my Bounder in tow mode even when not towing a vehicle or small utility trailer? Anyone install 5 Star on the Ford V10? Love to hear feedback.
Thanks
Your Bounder is very heavy to start with so absolutely yes, by all means enable the Tow/Haul mode.
Ford's Tow/Haul mode enables automatic hill descent downshifting (saves you from manually needing to downshift when going down hills and if you feel the need to downshift further just press on the brake pedal then let off after it downshifts).
Tow/Haul mode automatically adjusts the shifting strategy for hauling and towing heavy loads (being you are in a heavy motorhome this is what you want). The shifting strategy will change shiftpoints to take better advantage of the engines HP/TQ which may include holding out upshift a bit longer.
As far as tuners, well 5Star is trying to sell you on the idea that you "need" their product, it is a "crummy commercial" and treat it as such.
Their tuner will further adjust shift points strategy and shifting pressures within the transmission. This may add additional stresses to your transmission that were not accounted for by the vehicle manufacturer so it is a "Buyer Be Aware" type of thing. Roll the dice and take your chances..
Would I add a tuner to any of my vehicles?
Nope..
You have a non turbo gas powered MH, treat it as such and it will live a long life.. Hop it up, and you run the risk of shortening the life of your rig.
Try using the Tow/Haul mode everytime you start your MH before dumping money into a tuner.
