Will there be problem's?
 

I'm planning on putting a RMR intake and Tanabe Concept Blue turbo back exhaust with the stock cat on my 06 MR.I wont have the money for a flash for about three month's and im wondering if doing these install's will they cause any problem's with no tune for that long?Any comment's would be helpful. :mitsu: :confused:

You will be fine...i did TBE, manual boost controller and a fuel pump and i didnt get a reflash for 2 months.
