Sprint poster question

Just installed my sprint booster only question really is the led in the button supposed to stay on when car switched off
 
I love it, after reading good and bad reviews I thought I would take the plunge. The car feels amazing on the green mode and how it should of come out of the factory definitely feels more responsive
 
+1 for washers. You only need a few mm, so it doesn't change the pedal location to much. As previously said, red is a bit much for the wet, but fun to flick it on for a quick blast.
 
I had the same experience after fitting the lightweight crank pulley. Throttle response was 2x better.
Sold my Sprint Booster couple days later.

It was undrivable even on green. Too aggressive. :smiley:

However. if you don't want to mess with the pulley - SB is a good way to go. It makes a nice difference when driving, but it makes it hard to ideally launch the car.
