Sorry to call BS, but I am calling BS. Firstly, I thought you were talking about your dad's pickup some time in the past? But now you refer to "my" transmission and in the present tense.
Secondly, a stock WRX of any series would whup 99% of pickup trucks, and in a straight line. What truck is it and how has it been modified? We're car nerds, we like such details!
Back on topic(!), I don't have a direct quote but have even seen it in these forums enough, I love when people who have a VTEC engine dress it up as some kind of performance enhancement, likening it to a turbocharger or fuel injection and banging on about the sound of it, when it is of course an efficiency system. Go optimum fuel economy!
