Give me some more info on this "Unichip" that you installed.
Since the K&N is sucking in hot air from the engine bay, odds are that you may have lost power from it, and the magnaflow exhaust could have cost a few h.p. on the bottom.
ALSO, I think the 4Runners have a shorter first gear than the Tacomas, but I cant find anything to back this up right now.
