Where to order a Sprint Booster?

I was wondering where I could purchase a Sprint Booster for my 2009 S550?

Do you guys have any suggestions?

Pros/Cons about the booster?

Thanks!

I personally do not recommend the booster. First off, it does not make the car any faster; it only accelerates the throttle opening faster than stock. So when you are pressing the pedal down 20% it might read 40% instead. At the end of the day 100% is still 100%, you can achieve the same goal by pressing down the throttle farther. What it does do is make it far more difficult to modulate the throttle with precision. I had it on my 211 and it lasted for 3 miles before I pulled over and ripped it out. I found the car jerked as you tried to smoothly accelerate. Certainly not something you want on an S class...

Do you mind telling me where you got your booster from?

There's a lot of traffic here so I would like the throttle to be more responsive for overtaking.
I also heard that downshifts are more responsive.

If you want to get one, I can get one for you, just give me a call.

I had it in my w211 for 3 yrs and loved it, not difficult at all. I tried it in my S but it threw off all sorts of errors so I had to pull it out. Wished I could have it working, keep us posted on what it does for you.

How was your MPG after installing your booster?
With the booster do I have the option to turn it on or off? Or is it just stuck?

Is there any other options to get more power from the V8 with simple tune ups? Only mod I have on it is a remapped ECU from Lorinser.

Thanks for all the replies guys (: really helpful

The sprint booster will give you absolutely zero extra power from the ECU. It will also have no affect on the the tranny shifting whatsoever. It does only one thing- it advances the position of the gas pedal. It has the EXACT same effect as pressing the pedal down a little farther, that's it.

FWIW- I purchased it from a forum member who did not care for it for $100. I then sold it for $100....
