New 500 Efi Throttle Body Upgrade

ANY ONE HAD OPPORTUNITY TO DO THE NEW THROTTLE BODY UPGRADE TO YOUR 500EFI AND MODIFY YOUR FUEL PRESSURE REGULATORS? WAS IT A DIFFICULT JOB? HOW LONG DID IT TAKE? HOW MANY TIMES DID YOU HAVE TO ADJUST REGULATORS TO MAINTAIN RECCOMMENDED FUEL PRESSURE? DID YOU HAVE TO DISSASSEMBLE FRONT SIDE OF ENGINE(ALTINATOR,FILTER MOUNTS, SEA PUMP ECT.) EACH TIME? WOULD YOU DO IT AGAIN?
WAS THE REWARD OR GAIN WORTH THE WORK?

boost power sells the upgrade kits they had an article in one of the boat mags a while back, going to the single blade throttle and regulator, looked nice, how much money is the upgrade?

Arizona Speed and Marine has one also to make a 500efi into 525hp. I think it is about $1400, I was told that it really doesn't make a difference and not worth the hassle??? If you do please let me know your results
