the string could have stretched , check your brace height

Your arrow is going faster.
That the string is much thinner and pushes the arrow from the bottom giving it an upwards attitude on launch as well as a tiny bit of archers paradox.
Are you using the same brace height?

yes its set right in the middle of the 2 lines

what scope? You may just have to adjust your settings all over again.. that string more than likely gave you 10-15fps which is why you are shooting high. Depending on the scope, you may need to adjust your 30-50 yard pins.

move back to 20 yards and go from there again... adjust for 30 and then 40

check the scope to make sure nothing loose also, but if you are shooting dead center high, then its not the scope. You just have to adjust for the 30-50 yard ranges

Do you have a speed ring on your scope?

its the vari zone scope hits dead on at 10 20 30 then forty is 8 inches high with a broadhead an field tip

yes has the speed ring

I had to adjust my speed ring up when I changed strings to a faster speed. Even faster than the chrony actual. THEN start at 20 again. And problem was solved.

If you follow the instrcutions in the scope manual you should have no problems. Here they are in case you don't have the manual:

1. Use a target for sighting which will safely stop your arrows
without damaging them.
2. Field points are excellent for zeroing your scope, but be sure
to adjust for your hunting arrows before going afield.
3. Begin at 10 yards using the bottom of the top post and firing
several shots to establish point of impact. Adjust windage or
elevation screws 4 clicks for each inch of movement required
to correct your arrow’s impact then fire shot to check. Repeat if
necessary to ensure point of impact is aligned.
4. Move back to 20 yards to fine tune your sighting and shoot several arrows using the crosshair. Any final adjustment will require 2 clicks per inch of correction. Replace caps and check other ranges to ensure that your crossbow’s trajectory aligns with the other aiming marks.
5. To set the range compensation markers to 10 yard trajectory spacing, turn the compensation ring to the correct FPS reading to match your crossbow velocity.
6. To fine tune, move back to a measured 50 yards and check your bow’s point of impact with the lowest (50 yd.) marker. If you hit high, make a small adjustment towards the higher velocity. If you hit low, adjust the opposite way. When your arrow hits exactly on the 50 yd.
marker, your VARI ZONE is perfectly tuned to your bow.

I find that for step 5 it requires some edumacated guestimation if you don't have a chrony. And even guys with chronies will tell you that the compensation ring marks don't always match up with the FPS. But it should be pretty close.

Good luck and good shooting!
