Finally got some time to do my 700cc bottle conversion which seems to drastically helped consistency it seems. Also changed out the valve spring to one that is in between the stock one and that lighter one I had to begin with. Got lots of new projectiles to send downrange. One of which is the Seneca pellet 43.2 grain which registered consistently over 80 FPE with the highest being 82 FPE Had regulator almost all the way up at 2800 psi and hammer spring all the way out. Side note I got a shipment of Zan slugs in and they are very nicely made. Was raining really bad here today so no grouping... Just chronograph info. I feel like with the even lighter spring I could easily go over 85 FPE.. attached is a screenshot of those figures. Those pellets are ugly as sin and don't fit in a magazine but they sure do pack a wallop.
Avenger .25 over 80 FPE!

Thank you. For all the avenger owners out there it seems that the spring weight is the largest influencer on power gains. Im sure the port work I did helped along with the power plenum but the gun picked up big time with the spring adjustment.That's zinging along nicely, good work.

Where did you get your spring at? Been looking for a while now, maybe I’m not looking hard enough. Also, how much did you pick up with just the spring mod?
Thanks

Picked up the spring from local hardware store. It is a 3/8" diameter spring. I got several in varying lengths and wire diameter. I believe the one I have in there now is a .035 wire diameter and 1.25" long.... I think. But if you compare the stock spring to the stuff at store you will easily be able to tell how much lighter they are.
