I put the next stiffest spring I had in it and it took it to about 11 psi through the exhaust, which is a good place to start IMO. I will try the regulator idea. In the meantime I put the rjc valve back on it and adjusted it to about 18 and all seems well. It momentarily spikes to 20 on spoolup and then drops back to about 18. Runs good enough for this guy for the time being.

Dont know how I ever lived without this scanmaster on the dash. I now own every TR specific scan tool ever made.
 
Had the same issue.
Went to harbor freight. $8 bucks
For regulator. $5 fitting. A few ft of hose
Problem solved. No creep or spikes
