If you don't know how to do it, your first option is to call FP. They're very helpful. I tried to put a FP WGA on my Black, but it just didn't fit, no matter what I did. I just boxed up the turbo and the actuator, and sent it back to FP, where they didn't call me names or suggest I was dumb, cheerfully did the necessary fitting up of the WGA and installed it on the Black, and sent it right back. While the FP turbos are precision built, they do need fitment of the WGA.

If you're going to try to do the fitment on the Forge yourself, you will need to take a careful look at the setup and decide what massaging is necessary to the WGA to make it fit properly. Then, you can set the preload to your preference and you're good to go.

I would not drive it too much with the system not operating properly. It's no fun, and could cause you problems with your car or your warranty...
