The change is night and day. Unreal.
In hindsight, I should have installed the SprintBooster in the dealer parking lot when I first took delivery of the vehicle.
Soo much more pleasurable to drive, be it around town or on the freeways. Finally feels like it has some real get up and go.
Engineer pass down to Ouray via CR18 is kinda hairy.
Same with Imogene Pass going from Ouray to Telluride.
Both doable in a stock 2017 4runner with stock sized KO2's and sliders, but there will be some white knuckle time unless you pick good lines. I often didn't.
Imogene Pass going...
