2005 f150. 5.4 Never had a programmer
85k miles. BBK 80mm throttle body, s&b CAI, champion spark Plugs, Gibson cat back "sport" exhaust. No Programmer "yet". Will one really help? And how hard to install. 87 octane. I drive allot of miles. Seems allittle sluggish. I'm up for any tips but not so far as to a supercharger. I wish
