I'll admit that I didnt know all that you just posted. But I was going to touch base on the topic of economy/mileage/ignition/ecu related etc. butttt my only quirk is, if Honda intentionally reduced torque knowing they could have eeked more out of the setup, then why did they choose a higher (numerically) final drive (a common honda "niche" to make up for lack of torque)?
iirc, 03-05 is j30a4, and 06 is j30a5
