Hmm...it's odd that the Rev limit option is missing on the website. I think you'd be fine with placing your order and when you get your confirmation email, reply back directly to RRRacing with the tune you want and they'll send the file your way after you provide them with your ECU info from the initial obd scan. They're pretty good at responding back with any questions via email.
