I installed a SprintBooster. My impression is 100% positive. My vehicle is a 2000 C230 Kompressor. Modified with an ASP crank pulley, as well as the obligatory MAF relocation, 4-Bar fuel pressure regulator and NGK BKR7E plugs. Exhaust is stock.
The vehicle behaves more intuitively now. Throttle lag is reduced to being barely perceptible. Transmission (722.6) interaction is greatly improved, with downshifting more positive, smoother shifting in 1-2 and 2-3, and a better driving experience in total.
I am using the Generation 1 Sprintbooster. Due to the fact the 722.6 is an adaptive transmission, I do not want the on/off feature of the Generation 2.
After initial installation (simple plug in) there was a period of driving when the fuel computer readapted. There was pinging in the engine. There were a few rough shifts. The car felt strange and it made me uncomfortable. In time, the computer adapted to what it was receiving from the throttle position sensor, and the results have been great.
I was sceptical about the sprint booster at first. I wondered if its simple programming would make any real difference. Could I simply reproduce the effect by changing my own throttle activation, i.e. Pressing the gas pedal faster evey time? The answer is NO. The act of driving a car requires intuitive mind-body-machine interaction. Mercedes built a time lag into the fuel computer, ostensibly to save fuel. To attempt to manually, purposefully remove this lag by foot control alone would be maddening.
I have tested the sprint booster in S mode, W mode, in reverse, on snow and ice, and with cruise control at various speeds. The device passed all of my examinations.
Highly Recommended.
