Rising Rate FMU?

I have noticed that nobody in the supra community uses a FMU to increase fuel pressure. It seems to me that if we used a second fuel pump and a FMU to increase fuel pressure based on boost, we could get alot more out of our stock fuel system. Multiple others use this method to get enough fuel from stock injectors even on cars that didn't come from the factory boosted like the Mustangs, LS1's, and honda guys to do turbo/supercharger kits to achieve additional horsepower. Is there a reason that nobody uses this technique on the MKIV? I noticed based on a search that somebody mentioned this in 2002 but there were not many responses. Seems like it would be a cheap easy way to get the extra fuel needed for a few more psi of boost. What do you guys think? :dunno:
