Porsche has been using F/I all it's life in racing, had no problems with it, infact promote it in every way. Compare a Porsche twin turbo 3.6L with a 400HP 5.7L LS1 motor. I bet that's harder to knit-pick, both have similar HP, similar torque, very reliable, and my money is on the smaller (and much lighter) F/I motor for fuel consumption, tunability and weight distribution effects on chassis dynamics.
You can't compare my 3.2L supercharged motor to anything.... it was never designed to accept boost, and with the wrong tuning... it blew up.
