Ok here's the story. I broke my stock intercooler so I had to fix it so I figured I would just upgrade it while I'm at it. So I bought ZZP Intercooler and catless DP. Now my question is should I put these on without a tune or save up and buy charge pipes and HP tune and have everything done at the same time.

 

you might want to tune for the catless DP or else you'll throw an emission code

 

I drove around for a couple months untuned with a IC and catless DP, I threw a code every now and then with the catless. If your planning to get tuned then its not a big deal.
