This performance module was key to all of my MODs performing as they should. The throttle response is crisp and when pulling through the RPMs and it feels strong. The shift points are higher feels much more performance oriented. My MODs include, Jet Performance Module stage 2, Jet Performance throttle body, full cold air intake, MSD coils, 8.5mm plug wires, shorty headers, throttle body spacer, high flow cats and exhaust. I do run 91+ octane and Royal Purple oil. 5 Stars!

Bought it cause I put 35's on my Tundra and I was about 5mph off comparing to GPS. Also noticed shift points were off along with gas mileage. This calibrator not only allows you to fine tune the speedometer but it also brings the shift points back to factory settings. I am now back to 18+mpg on highway and 13-14 aound town and I am heavy on the right foot. Easy install, just make sure to zip tie to prevent rattles behind the dash. Highly recommend.
