Gas mileage with GET SX1 ECU
I have a 2021 450RL with the GET SX1. I also have a full FMF Q4 exhaust and Twin Air filter (no backfire screen), stock gearing. I did a three day off-road trip and ran it on the "enduro" map thinking the lower power setting would result in the best gas mileage. I ran out of gas once but fortunately my buddy was carrying a rotopack. I was only getting 30mpg on a mix of pavement and fairly mild dirt roads. I asked TacoMoto about it and the said the enduro map is not the best for range.
I did another trip using the high power map and got 46mpg on about 60/40 mix of road and dirt. Better but still seems low for a single. Is it unreasonable to expect better milage? I have a 3 gallon IMS tank on it but plan more long dual sport rides where fuel is far between. Should I just carry more gas?
