MuchoBeerOne,

Honestly I can't tell any difference between the 475hp XL Liberty and the 500hp H3-45 Marathon. It may be the extra weight in the H3 is the compensating factor.

It seems that the H3 has little less turbo boost, but it just might be the gauges as the new dashboard gauges (looks like a chevy dashboard) don't seem to be as sensitive as the nice truck ones in the XL.
