Air box mods

[Dinger]

Taking this into account I removed my maf housing and measured it up yesterday, the ID has a 2.5mm tapper in it with it being larger on the in going side. So I chucked it in the lathe and removed the taper. To try and slow the airspeed over the maf as I could only get 14psi, with moderate spool up, before getting limp mode. First thing I noticed was how much smoother it is at idle.(my passenger side airbag used to vibrate). I have uped my boost to 16psi now and have had limp mode once since. I'm gunner take another .5mm out on Monday and see how it go's. Is the hpd housing I'd straight through or tapered?

From looking at mine I think it was straight through the taper is on the outside. The area where the MAF is located is thicker. I can check mine on Friday if you need exact.
I am running 17psi now with no issues.
How did the stainless end up?
