After some searching, I came across Fiveology Racing (fiveologyracing.com). I spoke with Brian Bastob about the MAF conversion and ultimately my near future plans for the GT. Fiveology offers three conversion kits for varying performance needs, and Brian can put together a MAF conversion kit tailored specifically for the 5.0 Mustang. I also upgraded to a 70mm throttle body and EGR spacer, so Brian set me up accordingly. The kit is complete with everything you'll need minus the throttle body and EGR spacer. Brian is also knowledgeable about this conversion and was helpful with our tech questions.
