S3 Pollution Plus+ Edition
Well the flutter is normal, but any great hesitation is probably due to the mapping/fueling. I think you should get the car read by VCDS and see if fuel requested is being met.
If it is, then no need to jump into fuel pumps unless you want to go further, i.e stage 2 or more.
If the fuel is being met, what else could cause the hesitation? Perhaps change the spark plugs for some cooler ones?
Make sure your using High octane fuel.
Contact revo for some finer tuning, Im sure they can fiddle with it somehow and make it more refined. My friends golf TFSI 2.0 stage 2+ REVO has seemless power. no hesistation, nothing, Just whaaaam. They did have the car for a week or so as they used his car as a test car for new software. So they are capable of producing good maps, probably just need to spend a bit more time with it at a guess.
My shark maps no different. It needs refining, but that will be at tackled stage 3.
