To those that have a Tundra, Tacoma, etc., there is a product called "Pedal Commander" on Amazon.com for ~ 290$ and this thing kicks ass, I'll tell ya'll.
My cousin and his 3 sons all have Toyotas (3 Tundras and a new Taco) and have these in their trucks. There are 4 settings and you'll not want to exceed the "City" mode. It's all in throttle response, not engine tuning, per se, does not affect the ECM module and does not show when scanning the computer like, say, if you had used an engine tuner. This thing takes all of 5 minutes to install and most of that holding the flashlight in the right position.
