I had mine on since at 150 km mark 2.5 years ago and have zero issues, coming up to 45,000 km.
I just ordered a Sprint Booster from Jason for my '23 SR5. Can't wait to give it a try!

I love the sprint booster! Having driven it for 4000 miles or so, both at altitude (11,000 feet) and at sea level. This absolutely gets rid of the notorious pedal lag that I suffered from when drove my new truck home. When I step on the gas, my truck GOES, the way it should. This is well worth the money, and I can’t imagine not having this. You won’t be disappointed!
