This past weekend I put on my Forge WGA and tubular o2 housing and did a few pulls to adjust my timing and AFR to get them where they ought to be. Anyway before the installs with the stock WGA the boost would sort of "hit" and then slowly taper off. With the new WGA it builds hard and doesn't taper much at all. Anyway here are my 2byte load graphs from before and after.. Does this look normal for the aftermarket HD actuators?

Before:



After:



Here is my DLL dyno graph also.

 

Interesting..

 

Looks normal to me. Using a MBC?

Ok, but not rpm control, that is why you see that "hump" in the boost curve with the actuator. You would see the same thing usually with the FP actuator as well.

This can be tuned out with a rpm based boost controller, or oem ecu controlled boost.

It's not a bad thing of course, but you do lose the "hit" without it.

 

You can play around with the preload on the WGA too. It took me a little while to "tweak" mine using the FP wga which is similiar.

 

I intially had it too tight and boost would start at 20psi and creep to 24.5.. I adjusted the rod per FP (3 full turns) and it sits steady at 19.2 without any boost control.
