Sprintbooster installed
I put a Sprintbooster in the E63 on Friday. Overall, quite pleased with it so far. I recognize some of it may just be in my head, but the change in responsiveness is pretty noticeable. I've been experimenting with the levels. Had it on Red 9 for a couple days without issue, but have noticed that whatever it does to boost the throttle while accelerating seems to occur during decel too. The car seems to hold the lower gear longer after I've let off the gas.
Overall, quite happy so far.

I may soon turn mine down. Still experimenting. I like that you don't need to keep the control module attached - keeps things tidier.
Thanks for your thoughts on the Sprintbooster in earlier threads. Your testimonials had me consider it.

I removed mine when my ECU came back from OETuning, as their throttle remapping improved responsiveness vs. OEM calibration. That said, I'm 15 months into my tune and thinking about how perfect 'Green' was for my daily commute. When I pulled the SB I noticed a crack in the connector, and SB was great at replacing it under warranty.
Tune + 'Red' would be ludicrous mode. Is anyone running this on their daily drive?
