I have an Accufab 65mm throttle body. On the top of the TB, is a curved tube in which a vacuum line is attached. This tube was always plugged up in my application.
This tube became loose and is now gone. So now i have a hole on top of my TB.
Since then, by Mustang idles MUCH better and it accelerates more smoothly though I had to adjust the idle and TPS settings. Cold starts have improved as well.
Is having a hole on top of my TB a bad thing (loss of horsepower) since air is escaping? The idles is now solid and i no longer have issues with it BUT if this mean losing horsepower, i'd rather go with a 70mm.
