GDI is just junk, i wouldn't want one if you gave it to me for free...
I don't know about GDI being junk, I've had too many of them problem free to make that statement. My current F150 has 375 horsepower and 470 lbs/ft of torque from 213 cu in.
Not sure I could get that kind of performance out of port fuel or a carburetor.
Never had a valve deposit problem with any of them.
