I've owned both althouh my Fox was a Speed Density car. With pullies, off road, flows and a k&n on both cars the Fox went 14.0 with a 2.73 gear. The Sn-95 had the same mods except for a 3.08 gear and it went 14.4. From what I know Speed Density cars ran a little better than Mass Air cars, but my SN-95 had a little better gear and was heavier so I'll call that a wash. As previously stated, the computers suck in SN-95's and the intakes arent the greatest, but it's not hard to get them to go fast.
