Installed a ScanGauge II in on '03 Tacoma 4x4.

As a test of accuracy for the horsepower x-gauge, I did an (old-mans version) of a fast takoff. From a stop, I did a smooth roll-on of the throttle to about 80 or 90% of available throttle, shifting at ~3500 RPM. Scanguage reported a reading of 135 horses which sounds pretty good cause the 2.7 I4 is rated at 150 horses.

Around town, on mostly flat land with small hills, it appears that my peak HP use is around 60 HP. Most of use is around 30 to 40 horses. I haven't scoped out highway travel yet.

If I were to replace the 2.7 I4 with a micro-diesel or electric motor, should I be looking at torque over horsepower ratings? Seems I recall an expression - something like - we don't drive horsepower, we drive the torque. Any other readings I should be looking at on the Scangauge?
