Spot on. I ride mountain bikes as well and folks spend gobs of money to "shave" grams off of their components when, as you allude, passing on the pizza could yield pounds of saved weight.Adjusting the engine management settings on a boxer has been proven to make it more responsive by moving settings away from the factory's settings, which are optimized for more efficient fuel consumption and consequently lower emissions. The remap can be used to bump settings into a range where you burn more fuel more quickly and can be adjusted o your specific riding needs (for best results this should probably be part of the intake and exhaust mods) and will definitely be perceptible as a performance "improvement" over middle of the road, global markets, factory settings. But let's not forget weight-to-power ratios which are critical on bikes. Our bike weighs in at a little less than 500lbs, I weigh (with all my gear and backpack, ready for my commute) about 250lbs (half again that much or around 33%). That's 110hp to move 750lbs. I'd spend a fortune dropping 20-30lbs off the bike itself compared to addressing the rider side of this equation and dropping my weight which would improve overall available "power".
