That converter circuit sounds like a good method. What kind of set resistor value would allow it to work for the 1998 11,250 hz limit.

You can get Ford MAF's that will do 2400 KG/hr for under $300 and soon ones that will register to 2800Kg/hour soon.

Combine that with this circuit, and it would give you a bang for the buck solution.

the engine goes into open loop mode at WOT right? Cant you just modify the TPS to only read 99% or something to that effect when the engine really is at WOT?

From the factory the pcm is set to be at WOT (and hence PE mode) conditions with ~ 60 percent throttle. I am not sure why you would not want to go into PE mode since we are talking about maxing the maf. Not going into PE mode would mean the pcm would try to maintain 14.7:1 AFR which would destroy the engine real quick. But yes you can at what point the pcm goes into PE mode.

If you wanted to dope out your own MAF transfer curve
another option is to go and port a Delphi 85mm. I did this
to my SLP MAF and even a little porting (just dressing off
the casting flash) drifted the cal by about 10%. So I think
it's reasonable that you could get 25% or more range
extension which by truck MAF scale would put you past
the 512g/sec table limit(?) for sure at 12KHz. Maybe not
a big deal but, perhaps enough for some at the lower to
moderate levels of boost? 'Course, you would have to
be ready with a wideband to get the table straightened
back up.

So after reading this, do yall think an SLP MAF would help jump up my stolck ls1's Hp?
