Solid build and if you are pumping 520 HP to the rear wheels that is impressive. If you are planning on running as often as you note in your build for 2022 , check out the Mustang Roundup in Hastings, Ne. in September ----- 3-4 days of timed track time available!
According to JPC, they don't start changing injectors and electronics until they add boost. It's still nearly stock compression too. Justin does recommend octane boost in the gas tank for track days. Added insurance. That is his words, not mine. Ported heads and intake, stage two cams and rotating assembly meant for NA. Plus RGR's "27 angle valve job" or whatever he called it. Many build their engines "for 1000hp" but never boost it. Well, a motor built for boost won't make as much power NA. The pistons are heavier and the rings are lower. Heavier rods etc. I wanted light and fast revving. Was looking for over 500hp
I sold my GT350 with the idea of paying some stuff off and still being able to get on track as much as possible. So I started the hunt for a turn key car ready to go. Everything on this car cost 1/4 what it would on the Shelby. Gets me on track a lot more.
