since you already own the vehicle, why worry about it? Especially if
you just bought it with the lifetime warranty.

I have not seen the dyno results you say, maybe if you could post a link.
But I have to note, that usually dyno results range from around 2000 rpm and
up. They don't tell you what is going on bellow 2000 rpm, and most of the
driving is in the 1200 - 2500 rpm range.

Mike is right. There is no substitute for a low-revving, high torque engine
with high rotational mass. Simple physics says Mike is right and you are
easily persuaded by marketing smoke and mirrors.

Some of my facts were off due to bad memory but here is the link to
the chart. It actually goes to low RPMs.
