I installed Sprint Booster v3 on my 2018 SR5P two weeks ago and am very happy with the results. I thoroughly researched this product and had been very skeptical due to the great deal of misinformation out there. This is a quality product and exceeded my expectations. It really improved throttle response and decreased pedal lag, but most importantly it gave me much more precise control of the pedal for easily tapping into a downshift. It’s great for traffic, merging into fast moving lanes of traffic, highway ramps, traveling up mountain highways and passing. So far, no change in mpg. Feels like a whole new vehicle and lets you enjoy the engine on streets and highways. I finally gave in and bought one, figuring that I could return it easily with the money-back guarantee if not satisfied. After experiencing it, I wouldn’t give it up. Like many others, wish I had done it sooner.
