My first installation attempt left the sensor module leaking air and causing a lean condition. 
That resulted in pinging.

I took another look and made some measurements of my C&L MAF sensor and the factory sensing module. It seems that the large diameter of the plastic part of the sensing module was about exactly the same diameter as the bore in the aluminum C&L unit. Obviously, there needs to be some clearance between the two pieces to allow then to fit together. A couple of minutes with a small file easily reduced the diameter of the plastic piece and allowed it to fit completely into the C&L unit.

Now, with the C&L unit re-installed and still running 87 octane gas, there is no hint of a ping! Increased power is back and it’s running great.  Lee Bender from C&L was quite helpful and in fact spent quite a bit of time on the phone with me discussing the MAF and sensor module.
