I don't know, that's why I am asking.

On the other hand, ditching the MAF, and starting over with a factory tune file and going the Speed Density route was almost effortless. 408, 248/254 cam, and FAST 90 setup has near perfect street manners during the ~1000 miles per week I drive it. 20+ mpg to boot.
Even with the weather around here switching from cool and no humidity to hot as **** with tons of humidity, the table needed only minor changes (which my fuel trims would take care of if I turned them back on)

Go SD I am, I read on here on another thread that stock Zo6 Maf flows just as well as SD so the way I read into that is get rid of it and save another 5lbs of the front of your motor all adds up you know.

Then the MAF Translator came out and saved the day for some of us... for a little while.
My car ran rich untuned w/ LT's, but nothing too bad. I observed 12.6:1 average doing pulls on the street w/ an LM1 hooked up. I switched to TSP duals and my car went dangerously lean vs. the ORY set up. The tune straightened that out, and greatly helped the area under the curve.
