HP tank and no shims? Master Tech please look

[1boobfromSector 7-G]

Hi,
I recently puchased a used 05 speed, after the speed was bought I learned that the orginally owner had been constantly using a HP tank on the gun. He also had removed all shims from the LPR. Now when adding shims or removing shims the LPR always reads right around 100PSI, and the inline reg. when screwed all the way in to decrease volicity it doesn't act as if it is doing a thing.
Now keep in mind I am not checking this gun over a chrono, but I am using the angel tool kit with guage to check the LPR. I was expecting the inline reg. to completely or almost completely shut off air to the gun when screwed in, does this sound correct to you on my expection of what screwing in the inline reg. should do?

Using an HP tank won't ruin anything. What he did when screwing around with the shims though is another thing altogether!

What I would do is to try and get the gun back to it's original state. After this is done and the gun is working properly THEN start messing around with it.

Disassemble the LPR assembly and visually inspect all parts for damage. Who knows, it may have been f'd up by the last guy who owned it. Replace the spring stack in the correct order using the correct number of springs. Make sure your pressure is good (if possible).

Dissasseble the minireg and inspect it. Do the same thing with the spring stack there also.

Make sure you use this opportunity to lube and oil.

After you can verify that the gun is in it's original condition then see if you have the same problem.
