I just resently installed the Sprint Booster -

after all the forums i read

I must let eveyrone know that on my

2005 BMW 545i this has been the best aftermarket part i have ever purchased.

I understand it does nothing to increase power. but it helps the 545i from its lazy feel-

MAN THE CAR FEELS AMAZING NOW!

driving on the RED Mode as SD is a bit toooo agressive. almost uncomfertable. but on the green and on

Gree MODE- and D-- the car feels so quick beefy and agile-

Best Choice i could have made


I may be over reacting but there is just no other way i can express how good i feel about the purchase.

Worth the 290$---
