So what is the consensus here on the board on sprint boosters for E63s? I did a search and there seemed to be opinions on boths sides of the fence with some naysayers eventually being won over. This all took place mid last year so I wanted to see what people thought of their SB's after having them for a year. Thanks in advance for any feedback provided.

 

I'll be getting it for my E63 soon. I loved it on my 545i SMG. The SMG shifts with the Sprint Booster and ECU remapped were lightning fast. I'm hoping I can duplicate it on the E63. I already have the remap and my shifts are still slow.

 

Its a great cheap mod for the 63 , it wakes up that slight delay and will make the car feel faster. Is the car really faster, no

 

Sprintboosters are great. Lots of tire burning fun. For extra fun throw in an "ecu reset".
