I am looking at getting a Megan o2 housing to get a little quicker spool. Is a tune necessary to see any gains with this mod? I imagine a tune will optimize the function of the housing, but I do not want to get a tune until I upgrade my injectors here in a couple months. I just dont see the point in paying to have the car tuned twice within two months. I guess it could be a pipedream, but I want to be able to put the o2 housing on now and see a little better spool up. What do you guys think? Install housing now, or wait until I install the injectors to put it on so I can get it all tuned in the same visit?

 

waiting is good.. thats what I would do..

Doing it all at once will give u better results and im sure ull enjoy it more! Dont forget to upgrade ur fuel pump..

 

Already have a walbro installed. Just looking to upgrade the injectors for when I want to turn up the boost.

 

You might get a little bit of boost creep, so I would adjust my boost accordingly.

 

I'd wait...get it all done at once

 

If I upgrade to a 10.5 hotside (which is the biggest, right?) do I need a tune?

 

Not critical, but it would be a good idea to get optimal effects out of the parts.

 

You don't need to updrage the injectors with stock turbo. In the early days that was the thinking and that is what was done. But you can run the turbo to the max and still run the stock injectors. I run 25-26psi on c16 with stock injectors and make 355whp

 

You don't need a tune for O2 housing any more than you need one for weather changes. It's good to adjust the tune for it but far from a necessity.

 

Could somebody elaborate?
