Installed the 451A sprintbooster on my 2003 C32, easy, except for getting the connector off, the release clips are pretty small.

I like the roller coaster feel of the sprintbooster. Its a lot more fun to drive, but like it should be. It would be nice if it was switchable. Currently, I put the transmission on W mode (wife mode) when driving with my wife.

Before the sprintbooster, I always turned off ESP, no more. Even with the ESP on, it lays scratch pretty easy.

The whole reason, I like as much HP as I can get, is for the feeling of acceleration, which is easier to access, around town, with the sprintbooster. The transmission downshifts quicker also.

Need to be careful about traction, now, maybe an LSD would help.

Thanks Jody for all your work.
