Arrow Sprint Booster (Or Similar)

Anyone running a Sprint Booster or Pedal Commander? I've noticed a significant lag between when I hit the accelerator pedal to when the car begins to move. I know this is partially due to driving manual vehicles forever and this being my first auto since 2015.

Here's info on the Sprint Booster:
"Designed specifically to enhance acceleration in a number of popular platforms, the Sprint Booster is an aftermarket electronic module that plugs in between the accelerator pedal and the engine control unit (ECU) in vehicles equipped with an electronic throttle control. Sprint Booster is an application-specific hardware based product designed specifically for your car. This device is engineered to improve acceleration on drive by-wire cars by continuously measuring and converting the digital signal providing the ECM (Electronic Control Module) with a new and altered signal. Many modern vehicles utilize electronic throttle control and more vehicles are going that way, especially performance and sports cars. In conventional throttle systems, the accelerator pedal is connected to the throttle by a cable. In electronic throttle control systems, the accelerator pedal is connected to a sensor that sends a signal to the ECU that operates the throttle. The ECU increases or decreases throttle effort based on your accelerator pedal input, however this doesnt always translate to instant response. Things like pedal sensitivity, stability control and traction control systems can vary on different vehicles and can also lead to larger lag in throttle response and acceleration when its go-time. Sprint Booster improves response, increases pedal input sensitivity and delivers more impressive off the line performance. This product does not alter fuel or ignition in your vehicle; its a simple plug-n-play mod that delivers instant response throughout the power band, making accelerating and revs matching incredibly more fun."


Just curious if anyone has one on their A3 and how they like it.

There is a vcds change that changes indirect to direct that works on mk7 golf tdi's, its in group 44. t might work on a3 tdi. It does exactly what this device claims to do, but its for free. It makes my mk7 golf much more fun to drive.

All of that goes away with the delete and tune. I just got done having Malone make a custom DSG tune for me and it is now the best it has ever been.

Also I saw your post on vortex about fuel mileage. Here are my last 10 fuel ups. This is driven by me and my wife and we both drive with a heavy foot
