2013 Mustang GTmanual dyno done today
160 miles on the odometer. Dynojet dyno located near Houston, Texas.
I'm well pleased for 377 rwhp, but IMHO the quarter mile time is more important. I don't know if this is true or not, but the guy at the dyno shop told me that 377 rwhp calculates to around 435 (+-5) at the engine.
