can someone tell what TB mod is. people keep talking about it but i cant seem to find out what it is.

 

Throttle body Modification is for Turbos, to help increase throttle response particualrly when cold, as well as reduce throttle body temp.

It does little to no help for a non turbo.

 

Search for the phrase "throttle body mod", and you'll find a lot of info.

There are actually several stages. If you live in a cold climate and drive the '7 during the winter, you probably don't want to remove the thermowax.
