They need to sell it as the supercharger and bracketry only... that's the way I can see them getting the most sales.
You'd be better off making the passenger fenderwell like the driver's side and then putting the maf in the fenderwell. That would take care of all your flow issues... especially since i'm not a big fan of blow-through maf setup to begin with.
You want that 90 deg bend out of there so the air is flowing through the tube uniformly... if you more air flowing on one side (which I believe it what happens when you have a bend) you can get innacurate reporting from the maf since it's in the middle of the tube.
Pro-M at one time was making a maf that had measuring spots all around the tube to account for intake designs like this.
