I used to have the original Sprintbooster on my W203 and loved it. It had so much more effect than it should have for a simple signal amplifier. I wondered has any one tried Sprintbooster 2 with the adjustable settings. Has anyone had one on a w204?
I notice Kleemann and Tuning box have similiar products.
Has anyone got any experience of any of them?
