Hello, I've been well and truly bitten and am now set on a throttle body after I've done the exhaust. Was gonna do bluefin too but seems remap is needed after throttle body anyway so no point bluefinning it.

My mechanical knowledge, lets assume is 0 on any scale. I can do nut and bolt changes etc.

The throttle body on pumaspeed is 67mm. The standard ST170 one is 66mm. Is 1mm really going to make that much difference or is there more to it.

Basically, has anyone got the above one, and are you happy with it. Also, was it really a 30 minute job?

Anything else need changing or is it a straight swap?
