Had my fj tuned recently. Need to source a different throttle body with iac because engine is struggling when thermos are on. My question is I can get an xf throttle as everyone seems to go for them for there fj. Is there any other reason other than size that they are prefered??
Also I have done a quick search and can get an ls1 body with all sensors or a ba turbo body with all sensor for around the hundred dollar mark. Would I go one of these over the xf?? Ba seems to have a massive iac.
Any thoughts other than it dosnt matter??
