Artic is right on! My 272 with a stock 502 ran a max of 63.4 5100 on gps last year with a worked 23 Mirage that came with the boat. I added Stainless Marine exhaust flashed the ECU and had Greg Hittner at Cutting Edge lab a 23p Mirage plus which he suggested I add some cup and shave down slighly it rides the bow up higher now and handle the rough better then ever! (GREAT WORK) Even after that only running 65.00 @ 5200 but I'm happy nice cruise and handles like a champ. All readings were with full tank loaded with cooler and beer :)
