Installing a box 5/16 thermal shield plenum on my 05 350Z
 

Misspelled BLOX* in the title.

Hey guys, I'm a newbie to remap/tuning so don't bash me. I want to get that plenum spacer, but I was just thinking that I needed to disconnect the battery, and I got an Uprev tune on my car. So will it cancel it out ? I read about base and real time tune, I kind of think I understood, so basically my Uprev tune is a base and disconnecting the battery won't change anything? Is that right? Just want to make sure ! Btw I am foreign as well, thanks again.:bowrofl:
