Very nice.
By way of background it was placed there specifically as a "test beater" to pass the unladen portion of FMVSS 105 and FMVSS 208 brake tests.
We also used specially trained brake test drivers who we knew could achieve the best stopping distances, to help ensure passing the test.
Lastly, there was no limit to how many attempts we could make so we could also keep testing until we got the truck/configuration to pass.
I say all this to say: removing the valve should not be a problem. It was released to address this one (very specific) test situation and not for general use or customer pleasability.
