Yeah, I'm glad I was understanding it correctly. As far as my experience, I'm still using the completely stock actuator with a few turns of preload. Recent logs at the track showd 28 psi max (mostly 27.7) falling to 25 with a very final at top of rpm of 23. Don't know if I'm just lucky with it holding fairly well, or what, but about a week before the thread using the external spring came out, I had decided to do that exact mod. I'll be testing it on the dyno as a final/final test during the cam comparisons.

 

on my stealth I have a vacuum canister and run a hose from that to the WGA so it helps pull the WG shut with vacuum.

looks like I'm going to be skipping this step, my 20g kit is for sale (see link in sig) I'm going 35R
