Dynamometer Testing Since we'd only just installed the supercharger at the time this article went to press, we didn't have enough drive time in the Tacoma to allow the truck to adjust to all of the changes that had been thrown at it. Typically, trucks that are controlled by a computer should be driven a few hundred miles to learn the changes that have been made to them. In only two days after testing, though, there was a marked increase in the amount of power that could be felt from the time we tightened the last bolt on the TRD supercharger kit. The following information was received from TRD using numbers from tests on a '02 Toyota Tacoma S-Runner equipped with the same engine and dynamometer-tested on a DynaPack Chassis Dynamometer. We'll amend these figures in an update in our next issue's MT News column to give you the account of what we got out of our own truck.
