Has anyone tried this? I pick one up at a junk yard since I didn't want to carve up my own. Anything special I need to know. One question I have now is - should I remove all of the backing plate that is behind the sampling tube? Thanks in advance to anyone that can share their wisdom with me.

 

Actually, I just finished it. The truck seems to rev a freer over 4500 RPM's, instead of wheezing like it used to. Didn't throw any codes either. Haven't had a chance to dyno it yet.
