Ya, the rcf had a super charger kit on it (638whp, absolute POS, luckily only bolt on) that i ended up removomg bc it was so much of a hassle and left me stranded a lot (i was one of the performance companys test cars) . Combo of where i live and a poorly designed system. I just had the audi tuned last year to 700whp. No longer have the rcf.
