I tried googling it, but i have yet to find anyting that tells me how this actually works and give any real conclusive tests or evidence that shows that its worth the money...

Anyone have one of these?

Thanks

it works, doesn't give any HP gains but shortens the delay when you stomp on the gas, so you feel like it's going faster.. a lot of MBs have them, a couple of reviews on mbworld

I can't recall the thread that I read on ScionLife about things like this, but the general conclusion was that they were gimmicks. The only way you're going to get all those benefits is to go to a throttle cable system.

I can't speak about this particular product, or the Scion version.
However, there is truth to the fact that throttle "tip-in" and how much pedal movement translate to acceleration, can be altered through programming.
The ETC is very much like a servo. If you are familiar with Radio Controlled cars, planes, boats, etc...then you know how a servo can be altered to provide a number of ways to control it's function.
The same can be done with the ETC in your car.

For example, you can set the servo to be very linear, thus there could be a ration of 1:1 where 1" of movement results in 1mm of throttle plate opening. You can set it to a 1:2 ratio where 1" opens the throttle 2mm.
Or, you can go 2:1, 1:4, 3:1, etc... This way you can change how much throttle pedal movement translates to throttle plate movement, thus changing the overall feel. Many car makers will be quite aggressive for the first initial portion of throttle travel thus creating a feeling that the car is quicker than it is, because they haven an aggressive tip-in where a slight push of the pedal results in a large movement of throttle plate.
Some cars get too aggressive and customers complain of a "touchy" or "aggressive" throttle.

You can also set how much plate movement moves as you press the pedal farther and farther. For example, you can set the plate to move at a ratio of 1:2 for the first 25% of pedal travel, then set it for 1:1 for the next 50%, and 1:.5 for the last 25%.

I don't know as I've never done it, but perhaps you could post a question asking if the VAG tool and software has throttle (ETC) changes that you could alter.

Also, the ETC in most modern cars is also "adaptive" in that the ECU starts to learn that the driver gives a certain throttle input but doesn't intend to accelerate that fast. So, after a while of "learning" the ECU alters the throttle curve making a certain amount of pedal travel result in less plate movement. This can feel as if the car has become a big "slow" or "sluggish" off the line. Driving a bit more aggressively or holding onto a gear longer can help alter the ECU to give back some quicker throttle response.

PG has a try before you buy program and a lot of the local VW community liked the way it felt.

I borrowed one but never installed it yet as I am still tuning my setup.

I've been running a Sprint Booster for about 3 months now. It does work although I now find the gas pedal to be a little too sensitive with my setup.
