Hi folks. I have a 2009 F-150 with the 5.4 and I was needing some suggestions. On my truck, I've got a couple mods. I have a Spectre CAI, DNA Longtube headers, and a custom 3.5" exhaust with a magnaflow straight through muffler. To get the maximum performance out of my truck, should I stick with the canned 93 octane tune from my i3 or is it worth my time to have a custom one done?
