Sent my pcm off for retune for switch to auto and nitrous kit. I was going to by a box to pull timing but tuner said I didn't need. I told him I didn't want timing pulled all the time just for nitrous. He said he could set up to recognize when nitrous was used and pull timing. I am not sure how this is done. Is this possible? I am hoping my timing isn't pulled always.

 

It won't be but what i don't like is that you won't be able to adjust the amount of timing if you wanted to. With a Timing box you are able to do so

 

agree, nice to be able to adjust a few degrees out when u change jet sizes
