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.

300fps wont help you from 278 except maybe shoot another 3 yrds with one pin. if you draw 32" it should be less with a loop because a loop added to your string puts the release farther away.also is your bowspoundage maxed out, bows perform there best at there higher settings. 278 is plenty fast i think if your shooting good just dont worry about it.

at that speed the deer will never know the difference...

Sounds a little slow. I have a 31.5 inch draw and get 275 fps with a 425 grain arrow from a bow with an IBO of 303. Bring it to the shop and have them check it out to make sure if you think it isn't performing like you think it should.

At that speed you shouldn't have any problems. I'm shooting a Trykon XL also and it will kill a deer graveyard dead at 278. There are many variables to take into account for a few fps and if it tears you up that it's not shooting faster take it to your local pro shop and see what they have to say. Could be your string silencers, string loop, or even the chrono. Honestly though you should be fine as long as you're accurate.
