He did use different springs... At first 7lb and then put 3lb springs in and had the exact same results, and this was using just spring pressure to run WG's... No controller. With both spring variations he would see boost climb to 7-8.9lbs.

LOL! My vote is one on each fender! And just start the tuning at 8lbs!

That's only 2 springs tried. He needs something lighter for less boost. Plus a spring isn't going to be exactly precise in controlling boost.

I know they're not exactly precise.... But do you not think a 3lb spring should see less boost, compared to a 7lb spring?

Not necessarily. I already explained to you my situation where light and heavy spring give the same boost.

Okay.... Well I guess the thing to do would be try a 1 or 2lb spring?

That's the smallest spring they have.

Yeah... I looked at their chart...

Maybe one of the gates are sticking, and not opening properly? This really makes no sense to me

Any updates? Did you figure out the boost creep/controller issue?
