Advice is more then welcome thnx

 

I installed the Sprint Booster and it made a world of difference in throttle response. They warn you that when it's on #3 (red) to be careful and for good reason. The car accelerates extremely fast on that setting. I think the feature is inactive for backing the car, it still feels the same, which makes it safe in reverse. the #2 (green) setting is where I leave mine. I think it is a better compromise. The Sprint Booster works for the way Mercedes has it's system programmed. I have read discussions where it does'nt have the same effect on American Cars. My other car is a Corvette and they say it's not worth the money for that car, but for my mercedes, it really works.

 

its useless if you have a ECU tune.......same thing jus sprint booster only helps the pick up.....ECU tune will give u more HP...
