Do you use a Pedalbox or Sprint Booster in your DSG equipped car?

[Jakeys]

My car (R36 as per sig) does not have the problems you are describing. If your car is truly taking three to four seconds to respond, you have a mechanical fault with the transmission. The DSG should be pretty close to instant, certainly faster than a conventional transmission.

Despite that, the Sprint Booster, and I know this is going to be contentious, is snake oil. It is a pointless waste of money. What it does is sit in between your accelerator pedal and ups the current sent slightly, up until about 80% pedal travel, at which point the car thinks you are sending 100% of pedal travel. That's all it does. There is literally zero performance benefit, the Sprint Booster "boost" can be achieved by pushing your foot about 1cm further than you normally would. After 80% travel on the pedal it stops doing anything at all. I bought one a while ago, tested and graphed this using VCDS data to prove this, and sold it on. There are some people on this forum who swear by it but factually and unarguably, all it does is make the car think you're pushing your foot a bit further. It only *feels* faster because it is emulating you putting your foot down so you go "Oh wow this is fast!" but in reality had you just pushed the pedal a touch further, you'd be getting the exact same result. It's a placebo effect, pure and simple.

tl;dr: My personal opinion is it's a waste of money, but the factual data is that it has no performance gain and it cannot possibly help your problem.

I haven't heard of the Pedalbox but if it sits between the car and the accelerator pedal and changes it, it's fundamentally identical to the Sprint Booster. The graph might be slightly different but the end result will be the same, the pedal can only tell the car how much you want it to accelerate from 0-100%, it cannot send that signal quicker (The pedal is not the bottleneck anyway the actual mechanical components and the ECU are) and it cannot send more than 100%.
