The 90mm Ford pegs on trucks with just a 6lb pulley most of the time. We're pegging the 90mm at 4700 on the Works 140 trucks with only 18 psi becuase of the huge volume of air the 140 moves. We've used both the C&L 95mm and the Pro-m 92mm, and both of those MAFs also peg at 4700rpms with the 140. Both of those MAFs also have tranfer curves that barely outflow the 90mm Ford.

What is the solution, or is there one?

I'd be interested in knowing something about this as well. I have all the bolt-ons on my 02HD and I can hit 4.9V on the stock 90MM maf at WOT every time. Assuming 5.0V is the ceiling, I'm already there and I'm only running a 6lb lower pulley.
From what I have read of the 85MM C&L that the L guys used instead of going to the OEM 90MM, they had major tunability issues...
Who out there has done a big MAF? Is custom an option? Who would do it?
