MAF... no.
But a MAP sensor can be a great help!!
For instance, on my old evo the stock MAP sensor was something like 2bar.. but when i slapped on a big snail, and had everything set up to run 45Psi i needed more MAP sensor, because it would max out. so you can only adjust fueling/timing etc so much.
Slapped in a 4bar MAP sensor, and that gave me a broader reference to be able to adjust everything else.
I think these trucks only run on a MAF sensor though. Unless you have a Diesel. They probably have a MAP sensor. lol.
