If you do, the studs will be that much stronger. You don't HAVE to. Many people are running 60+psi without tapping....

Bump.. need more opinions
i didnt tap the holes on my truck nor did i tap the holes on the NGM race truck. both trucks have seen alot of daily driving and both trucks have seen over 60 psi! heck with one of the turbos we tested on the NGM truck we saw close to 80 psi.
Do you need too?? Probably not. But it's a good idea to clean the bottom of the holes out.
