Hello! Can you tell me where can i order the sprint booster? I would like to try it. Thanks

You can keep checking the forums because somebody seems to be selling a used Sprint Booster every few weeks or so like this thread yesterday http://forums.e60.net/index.php?showtopic=71199&hl= but they usually get picked up really quick.. in that thread somebody provides a link for an Ebay seller for the SB.. good luck!

The sprint booster has little to no effect at low speeds when little throttle is applied. I was scared to back out of my garage when I installed it but at low speeds with low pressure on the gas it won't ram your car into the wall. At higher speeds 50-60mph when you stomp the pedal it'll downshift and you'll be in your 3000-4000rpm torque range and take off. At 20-30mph when you stomp the pedal it'll rip your freaking head off! Sprint booster does exactly what you would expect. It's like it knows lol.

thanks Krozi for the detailed answer. I think I lll try one.

UPDATE!!!!!!!!!

I emailed Boulekos Dynamic and they told me I have to wait ten minutes after shutting off the engine before installing it or it will give me an error message. So I waited 10 min installed it and YAAAAAAAY it did not give me an error message.

I drove it around a little bit and here is my impression:

HOLY BALLS!!!!

I press it down a little and if shifts down SUPER FAST!! This thing is all I ever dreamed! I thought it was going to be all touchy feely and difficult to control but you can definitely control it. It is amazingly PERFECT!

Another Sprint Booster Convert! I forgot that I had mine installed, I just got used to it and then I drove a friends 525 and I thought, where the hell is the pick-up in his car? I even mentioned it to him before I remembered the SB in my car. Oooops! Anyway, welcome to the SB convert club!
