catback and PROcede question

twinturbopg · 04-07-2010, 05:04 PM

hi guys I did a quick search and couldn't find anything on it....

I'm running V3 Rev1 and was planning on running cat back exhaust which I have been told it deletes the secondary cat you down pipe and your primary cat is stock.

My question is do I need an O2 sim for this or something? or change some particular settings in my maps? I'm running stage 1 11-2 6AT maps. Or do I just have to upgrade my chip to a Rev2 which I would like to hold off for now.

I also have DCI & Scoops.

If you do you where I can find this information please provide me a link thanks!
