Swamp probably covered it, but here is the info you need.
You need module change and draw stop setting. If your bow came set up with 25" and your friend just moved the draw stop without changing the module, then all you need to do is change the draw stop back to where it suppose to. Otherwise, you'll need to change the module. Check the module # against this chart and see if you have the correct module. Then set the draw stop.

That is excellent logic, and thank you for pulling the mod chart... thats a huge help.
Rem girl it depends on how competent your friend was with archery equipment if he removed the mod or not... lots of folks see that post and instantly assume thats how the draw is controlled.
Easiest way to tell if he changed it... in addition to checking that mod chart, is to just draw the bow... if the stop is NOT hitting the limb.... then he just moved the post... all you have to do is loosen the set and slide it a bit closer to #1 and you are right back where you were.... you might even see some markings from your bolt where it was before he moved it.
