Yeah, sure... but what these dyno run charts fail to show us is what the impact will be on gas milage. A 25% increase which is accompanied by a 20% increase in fuel usage is not my idea of a good performance.
Nice stats? Sure. But where is the missing piece? What's it gonna cost us?
Now then... if that 25% increase was realized along with a, say, 10% increase in miles-per-gallon, now THAT is a performance increase that is truly worthwhile.
My 2¢ worth.
Be well & happy.
