thinking about buying a used WMS velocity tube with the PRO-M 87mm MAF unit. What hardware should come with this to install into the fender? Is there a piece that goes from the TB to the MAF unit that is made by WMS racing or has anyone used the Desencharger piece with the WMS setup?

I use one screw to secure my WMS to the fenderwell. It comes with a K&N from WMS and includes a hose clamp. There is no PP to the TB. Not much to it, just a 90 degree elbow that connects to a MAF.
I made my own PP to the TB.

what kind of gains did you see on your setup?

Hard to tell. I tried my stock MAF with the WMS first and got 1 Rwhp and 4.5 Rwtq on the dyno. Then I added a Pro-M 87 with a MAC H pipe w/cats and got got 15 more Rwhp and 10 more Rwtq on the same dyno. Mine definetely ran smoother through the entire RPM range with that combo, like night and day.
