Got my RSC tuned ECU's back in and the car "feels" quicker, especially at WOT against my RS7. It seems to really perk up at around 3500rpm, and I swear the car sounds a bit different though the tune should have no bearing on exhaust note. A friend of mine has a Huracan with exhaust, and we are going to do some side by side runes (in sport mode) after the Holiday. I'll post then and we will video the runs and post to this thread.
