If it's a Pro Elite with Spiral X cams, then it's 2009 edition.
Pro Elite was released in 2004, was on Spiral cams 2004, 2005 and 2006. C2 cams for 2007, 2008. Then Spiral X cams for 2009.
So you've probably got a 2009. The tune chart for this is
here. However, if you've got a 3.0 cam it should be 29.0" draw to start with. There's the ability to mess around +/- 0.5" using the cables on these bows, but 0.75" sounds like something is wrong.
Start by checking the axle to axle, it should be 39 7/8" measured between the centre of each axle, or very close to that. If it's over 40.5" then you need to put twists in the yoke cable to get it back - how old are the strings? It may be a case that they're just very old and have stretched.
If you get it back to box specs (ie 29.0") and it's still too long, then you can install the peg on the bottom cam in one of the other holes. Standard is the furthest away from the string (see lowest circled bit in picture below), the other holes knock off draw length and increase holding weight. You'll need to retime with the control cable but it'll drop your draw length.

In terms of how you set these up, it's pretty straight forward. You mess with the
yoke cable (the one that splits and attaches to the top axle) to get the draw length roughly right, bearing in mind this also impacts axle to axle and therefore draw weight. Once that's right, you use the
control cable (the one that doesn't split and isn't the string) to get the timing between the cams right, so that the peg on the bottom cam and the flat spot on the top cam hit at the same time (or however you prefer). Then you play with the
string to fine tune your draw length.
If after all this you really do need shorter cams, you're in a bit of a pickle. On the far right of the
tune chart you see it refers to Cam Family. You'd be going from family 2 to family 1, which means you'd lose between 3 and 5 pounds of draw weight. Not sure how important that is to you. The issue you'll have is finding them.
Hoyt cams like this ran in a series:
- Spiral
- C2
- Spiral X
- Spiral Pro
- SVX
Good news is Spiral and Spiral X are the same cam with only some minor tweaks. C2 is very different, and the later Spiral Pro and SVX are different enough you can't just swap them in without having to guess some string and cable lengths. So you need to find either Spiral or Spiral X - a shop may have a set of 2.5s hanging around, but you'll have to actually call and ask because it's unlikely to be listed on the website! Alternatively try the Archerytalk.com classifieds, there's usually lots of stuff there and while you're looking for an old part people may well have something. If you were longer draw length, I've got every size from 4.0 to 6.5 in my bits box upstairs...
