I put one on my 2012 Toyota Tundra and was blown away by the change it made on the throttle curve! At sport 2 mode full on, there is NO throttle lag, ( and I thought my truck was quick off the line stock) - it's just all, right now to the rear wheels! It's going to surprise you! And I like the fact that you can also tone it way down, which I'm looking forward to seeing what mileage increase I can get from a tank of fuel. Extremely happy with this purchase!
