I just picked up a ford racing 62mm throttle body. Is this bolt in and go part or do I "Need" to get the car tuned? This will be my last power upgrade. Car currently has headers and exhaust. No tune yet.
From what I read online, the ford racing manifold is either love it or hate it part on a N/A car. If I have more mods done such as cams, UD pulleys and delete plates like you said, the manifold will make sense but I don’t think I will go that far. I like to keep mods simple and have stock like driveability on all my cars. Lower end torque is important for me. I will discuss this with my mechanic and the tuner and report back.From when I was having some tuning stuff done they said the throttle body needs a tune, and switching throttle bodies required a complete tune re-write compared to some other mods that might not. I'm not sure if that's 100% true but thats what they told me.
If you're going through the trouble of a tune, and already have headers and exhaust you may want to consider the charge motion delete plates, or Ford Racing intake. From what I've read/seen with non boosted cars it mostly helps with higher RPM running but if you're tearing up some canyons you're probably mostly in the higher RPM range. I recently installed the FR intake and while I am boosted I noticed a huge improvement in throttle response without the control valves. My intake had them built in, which I think they started in 09. But making this change will need a tune also so it could make sense to pay for the tune once.
