Hey guys, just had a quick question. I just got my catless mpx catback delivered today and plan to install it tomorrow. I already have a K&N SRI installed and I plan to put the trifecta tune on next. I plan on doing a few more performance upgrades (money permitting) like putting charge pipes and stuff on, so I was wondering if I should do all that before I drop the money on the tune? I know I would probably have to re-tune for the new piping and stuff correct? I don't want the car to run crappy with the current mods I will have either so I'm kind of torn on what to do. Tried to search the topic but couldn't really find much. Thanks in advance.

 

In theory you shouldnt need to tune for the piping But do it anyways.

 

You do not need to wait to get it tuned at best if you wait it might be worth a couple hp but proly not

I am however curious when you say catless catback did you get a catless downpipe and a catback or....

 

u don't have to but u rist blowing the plastic pipes and intercooler end tanks on tune. intercooler not as much but it does happen
