Sprint booster..
you can also get it from Ebay from partsexporter (ebay@partsexporter.com)

it makes throttle response much sharper, even in D mode, you get much faster throttle and kickdown response than stock sport mode, i got my car a AFE CAI with remus exhaust, now just need to remap the ecu to optimize the hardware..

the installation guide is in the diy section of the forum, its pretty simple and straightward.

 

really thats god, does it at all give the car any mid range pull, torque, or is it most from standstill,
and just thing, does consume more fuel?

Let me know

Thanks

i checked that link on internet and it didnt return any results, can this sprint booster be done by me, through idrive or is there some mechanical work?
Is it a common mod for these E60,s . What your experience

Let me know

Thanks

 

SB basically takes away the native throttle delay built in your car and makes throttle response sharper - but a remap includes a sharper throttle response as well (but doesn't reduce it to zero).
I don't like the idea of bringing down the throttle delay to 0. BMW engineers built it in for a reason.

if you're looking for more power after a remap, you're looking for a more powerful car altogether IMO...
