I guys, I recieved a new trykon xl lastyear, I got it because the vextrix draw was too short for me. I am 6'4 1'2 and have a 32 inch draw, 32 1/2 with loop. However with my setup at 70lbs I think my bow is underpreforming.

I see so many people on this board talk about how there trykon and trykon xl are going 285 and higher with 29 and 30 inch draws,

i thought an inch in drawwould make your arrow go almost 10fps faster, but when I tested mine using easton st. epic arrows 400g "including tip"
i got about 278.

is something wrong with my bow do I need to get it tuned or something, is this normal and is it possible to get my bow to shoot 300fps or faster.
