Actually that is not a misprint. We have been testing 5 port stuff for awhile which is in the MTE engine. We definitely prefer the 3 port, they have been forcing us to run the 5 port stuff. I think Jared is running a 5 port, pretty sure. We do use a 2013 pipe. The run time on the 3 port is awesome. We have been able to get 12 minutes fairly easy. Any time you have an engine that goes 12+ minutes it's a combination of things to get that mileage, including tune and driver. (unless you choke out the engine with a .12 carb)
