Should I cvc tune and re gear 21st pro ?

Hi guys finally made it to Tacoma world
I have some questions.
Is there any effects of re gearing or cvc tuning my 21 pro or no.plus I’m doing wescott trd pro lift and was wondering what’s the best tire size for my stock rims without rubbing or cmc or changing the rims in general thanks

 

You want to know about a tune & rims/tires. Nice, a double whammy.

 

You're going to have to give a little more background on your needs. That's like asking "what's the best sock?"

 

Get the tune before the re-gear. You may find you dont need to.

 

Yes, regearing and tuning your truck will effect it.
