5startuning and Powertrain Warranty
I am definitely not an expert, but here is the reason I purchased the 5startuning despite concerns about the powertrain warranty:
1. After searching the irv2 forums (and this one), I have yet to find a single person who had an issue with their powertrain warranty after custom tuning. The Magnuson-Moss Act places the due diligence on Ford to prove that any powertrain issue is a direct result of the custom tuning.
2. Living in the mountains, I am willing to take the (small) potential risk of a warranty issue to benefit from the better drivability.
3. My goal is to keep it out of the shop - I believe that controlling the shifting pattern to keep it 3000-3500 RPM going up the mountain takes a lot of stress off the powertrain compared to 4000-4500 RPM.
Again, this is just my opinion and almost everyone on this forum has more experience with the RV lifestyle/mechanics than me.
Happy campers :-)
