Thank you!
Honestly, I'd say they would be neck and neck - possibly the NSX a hair quicker off of the line. I've also driven our FBO/tuned McLaren 570S & MP4-12C too and the NSX is every bit as fast in my book; I think the McLarens would ultimately have the edge though in the top end.
Those McLarens do put down some crazy trap speeds that's for sure!
Looking forward to numbers from the tune before I purchase anything!
