EVO 11.5 Hotside, anybody try it?
I hope that your new actuator arrives from FP today. Otherwise we'd have to wait until next week for results, huh? We is dyin' to know! I imagine that we'd all be pretty antsy by then.
In the meantime, you might want to try cutting about 3/8-1/4" off the threaded tip of your stock actuator rod. Also, dispense with the backup nut as well, as this is only there as a positioning reference during initial setup and adjustment.
So, remove the nut and toss it in the garbage bin. Using a hacksaw, cleanly cut about 3 to 4 threads off the tip of the actuator rod. This will allow you to bottom the turnbuckle out further down on the threads generating more spring pressure.

i have been running my 71HTA with this hotside for about three weeks now. i have the FP 18 psi WGA and it runs great. I made 2 more hp on 1psi less boost then my Tommi 6.5 turbo. 310 hp 315 tq at 22 psi
Added the spring, now its hitting about 26psi, holding 18psi up top... this is still with the wga vacuum nipple open to atmosphere. The turbo sounds kind of odd so i'm going to do a boost leak test and wait for the FP 25psi WGA. Sorry guys.
Guerillah: Maybe you mentioned it in an earlier post, but I am too lazy to backtrack. Just how are you controlling boost in your setup. I couldn't find mention of it in your modlist. If it was me, I would reconnect the vacuum hose to the WGA's nipple and not be running it VTA.
