I also found a hacker in D class 1230 multiplayer. The opponents were really tough. We made way sharper turns and were too accurate, and competing for first, but at last we knew someone was 13 second earlier than us. We have difference of .1 and .5 seconds. We thought we were the first and our numbers were just glitch, because we were almost together all the time. The hacker was already off the radar.
Tap break first n nitro after very fast. It Took me whole week of practice to get used to it. That Sector 8 Corner will be your best map to practice Punch Drift.
