Is there a bend in front of the MAF? That's the main thing you want to avoid. When I had the Densecharger on my car it would ping in cold weather because the MAF reading was not reading correctly. The tune compensated for it in "normal" weather, but when it got cold it made enough of a difference that it went a little lean. Swapped to the JLT, didn't change anything else, and all of the cold-weather pinging went away.
