here we go again,, sending out the throttle body to hp. inc getting the full port and puching it out to 48mm. getting rid of the pcIII and going with tts mastertune,,, and i thought i was done,,,lmao! there are guys here with the same power output with the tts and almost double the fuel mileage than me

 

What are the claims on the port job? I am also considering ditching the pc3. My 2008 StreetBob with the V&H Power Commander, slip ons and Drak air cleaner assembly ran way better than my 2011 SGC with the pc3, Straight Shots and S&S air cleaner..

 

if you take the time to uprade your heads, cams, exhaust, etc. you really should do the throttle body because it becomes the choke point of the build, stock harley throttle bodies arent known for performance, i took a look into it when the motor was apart and i could see it needed some work but opted not to do it at that time "MISTAKE" a good port job and a 3mm larger throttle plate will yeild almost 30 more cfm ,and a good set of head will really like that
