I tried this tweak for a while and noticed a faster throttle response, albeit subtle difference. I lost several MPG and I had concern that it might affect the longevity of my DSG and haldex.
I ended up changing my mind about the DSG and haldex because i plan on doing frequent fluid changes, allow decent warmup time, don't ever use launch control, and it's not common to see issues with slippage. So i'm hoping those last
I wanted something better so I went with the burger pedal tuner. it's a game changer and i've actually considered getting rid of my JB4 because i really wanted a more responsive throttle, but that's something that a DSG tune or pedal tuner could do. It's got a bunch of settings for how quickly it amplifies you throttle input. I keep it on stage 3 in the middle for fine tuning, but to be honest I didn't notice much of a difference between the stages. my MPG went down slightly after I installed, but that was to be expected and it's a money worthy mod because of how much it changes the throttle response. night and day
