BORED TB
Im just getting ready to install some new headers and figured i bore and clean out the throttle body.
My buddys dad owns a machine shop so i can have it done next to nothing.
MY question is:
1-What is the max i can bore it out without any other mods
2-Should i put a taper on it?
3-Will my computer adjust/check engine light

that should help you.
Also, You should not get a CEL after doing this, I would reset the computer though. So It can see the extra airflow
