if you look at the data on right hp and tq are the same @ 5250 tq is nice and flat till about 4000 so if your not a high rev rider should be ok

My stage 1 88 makes less torque but more hp than yours. Your power seems to be falling off early like she needs more air...

that makes sense the chart should intersect where the numbers say, definite error. I am going to the Burst collection air cleaner now. I was expecting a little more hp. It is a totally different bike than stock

thanks guys

Not that bad for a Stage I with true duals, a crappy air filter, EPA cams and an auto tune. Strap on a Dragula 2:1 or V&H Propipe, SE air filter and get the engine tuned on a dyno; she will wake up. Of course, a set of Andrews 48 cams will make a huge difference, even if you keep the TDs.

Like already said, A good cam will help hold more torque in the higher RPM range and thus increase the HP number.
