looks like there is a lot more room to grow from the dyno chart i saw on the lht forum. looks to me like the fuel curve is a tad rich and could stand some smoothing. also im not sure what the timing is like in that map either. u could probably find out from hondata tho. a better header and a real dyno tune would definately give you gains EVERYWHERE in the power band from what that graph looks like....regardless of rpm showing or not.
