Just a comment for you folks buying the sprint-booster. I've put a few hundred miles on the car with this installed and it still runs the same as the day it was installed. All I can say is this thing is great. Say goodbye to all throttle lag and slow take-off. I let my son-in-law drive it after I installed it and didn’t tell him I did any mods. When he came back he asked if I had installed a supercharger in it. He could not believe a $300.00 part could make such a change in pick-up.
