Definetely makes a difference off the line. I normally drive in "sport" mode so it's sharper than it was before.
hasn't completely cured this problem I have sometimes when I come off a longish period of constant speed, and then need to accelerate quickly. There's still annoying delay, but perhaps less than it was. There's still a 'hole' when I accelerate hard from a slow speed. Not sure if it's turbo lag or a slight error in gearbox change. It happens even with traction control off..
But yes, I reckon it's worth trying this pedal tuner.
Let me know how you go with install given our cars are the RHD. At the moment I have the cable running along the edge of my floor mat back towards the driver seat and then I leave the control unit on the floor under the seat. There's just enough slack to lift the unit and make adjustments. But I don't like the cable almost touching the pedal.
It might be cleaner to run the cable upward from the accelerator and attach it under the steering column area and then attach the control unit somewhere near the drive experience switch... I'll try that one day when the temp in my Canberra garage is not 5c
