im wondering if anyone has an new 2012 sho that has done any mods to? i have put a filter directly on the sc and did the free flow exhaust mod as per tommy`s post i believe... ihave 2 hrs on it and before was getting 67 mph, now it at 69mph but is surging at wot.. i know this is the rev limiter kicking in as i cannot go past 3/4 throttle now without the surging. i know these are new and some of the parts arent available yet,like the intake grate... i am wondering what impeller you guys would recomend? is it the same as the older sho`s or is it different with the new hull? thanks
