Hi. I have a stage 1 map on my 2011 2.0 TFSi Quattro Dynamik. I have noticed lately that whilst accelerating on a half throttle i get a 'surging' or 'pulsing' during the acceleration. If i put the foot down it goes away but every time its not a flat out acceleration i get a wierd on off type feeling from the car. Its not a violent surging more like if you gently accelerated then took the foot off and accelerated again over and over.
