Yes, they are, it's simply math, and I don't say that to be rude, I mean it very literally - you can't escape a 27% change in gearing and have it be anything close to the same. The 290HP engine (28% increase in HP) and 3.07:1 (27% decrease in gear ratio) roughly cancel each other out.asked about pedal cause others with the 290hp and gears are NOT having same losses your reporting.
Maybe they don't notice or care, or maybe they swapped to the 290HP and 3.07:1 gears at roughly the same time and so didn't experience much change all at once? I don't know. But I had my 290HP engine for a couple of years before the gear swap last year, and I find the change in pulling/climbing ability very obviously noticeable (no engine changes between the gear swap). So I experienced the nice change to the increased HP, and then the poor change to the higher gearing.
