Anyone race an F1000 with a Pipe? Says 16.6hp increase

[SledFreak]

There were several guys last year that burned down there sleds with only bullsyes and Y-pipes.. they went lean..

Some sleds run slightly leaner than others..

Yes, I believe that were the guys that went with the 2nd reflash. The first runs fine. My friend has 2000miles of only 87octane, no boondocker, y-pipe and bullseye. But, I think it's it's close, not much room to breath..
