I would like to hear more on what you have to say.
Just have seen variations in that same 85mm 5 wire MAF you are talking about in various GM applications.
As I mentioned a 2003 Tahoe 5.3 has a vastly different MAF transfer table than a 2004 LS6 Corvette. The Corvette MAF table is my go to calibration for startup for LS swaps with the MAF connected to the throttle body via a short straight intake tube. If you run the stock truck MAF table I have seen MAF codes with that setup and the fueling is way off. The problem is compunded when people put a short silicone hose off the throttle body and a cone filter on the MAF.
