Hello,

I have a 2018 WRX with about 2,000 miles on it.
I have purchased two things so far:

- Cobb Accessport V3
- Mishimoto Cold Air Intake and Box

For now, I want to install the intake and run it safely with the Cobb Accessport, although I don't know what tune to run. Do I run the OTS Cobb Stage 1 tune? Do I use a beta Stage 1+ tune Cobb created for a 2017 WRX with Mishimoto CAI? (If that's the case does it matter that mine is a 2018 and I'd be using the 2017 map? If not, why would they provide separate maps for each year?) ***Link provided below***

That is my first question.

My second question is, once I figure that out, I will also be buying a Nameless Muffler Delete in the near future. Will I need to make any changes to the tune or find an entirely new tune if add the muffler delete?

These are my main questions right now. It would be greatly appreciated if you experienced individuals could help a brother out!

Much appreciated.

I don't believe Cobb maintains the mishimoto intake tunes anymore so I would avoid it personally.

No tune needed for the muffler delete.

I wouldnt use any tune that wasnt specifically made for the named mods you have. The FA20 is very sensitive to airbox changes. Call COBB and ask. THEY will give you the correct answer.

Yup, you will need a custom tune for the CAI. I'd sell it and go with MAP's CAI and stage 1 tune, it's much better than COBB's.

Thank you guys for your input.
I called Cobb like you said, and they were very helpful.

I told them I have a Mishimoto intake and they said they do not have a map that supports that intake and that the only way to run it safely with that intake would be to get a protune.

They recommended I get a Cobb Big SF Intake and run their Stage 1+BigSF MAP and that it would be perfectly fine this way.

Also, despite all that I have heard from people on forums saying you need a tune for a catback exhaust, they informed me that anything catback (including muffler delete), does NOT require a tune. They said you only need a tune if you change your downpipe, because that is where the O2 sensors are.

So long story short, I will sell my Mishimoto CAI, purchase a Cobb BigSF air intake, run the Stage 1+BigSF tune, add a muffler delete, and be perfectly fine.

Hopefully this helps others that are in a similar situation to mine!

What forums? Can't say I've ever seen anyone say that..

Injectors? Fuel Injectors? What for?

 

[Maddtvguy86]

Because you know you are going to get a down pipe and thats all thats left.
