Hi All


Just looking for some advice please. I bought a 2004 WRX a few weeks ago and it has a full 2.5 de cat exhaust and downpipe fitted and it was already mapped with it on but I have a Blitz Nur Spec R which I want to fit do I need another remap or can I get away with it.



Many thanks

 

may or may not, no way to tell for sure without checking. should be ok but best bet get it on a dyno to check afr etc and then you will know either way

 

+1 for rolling road after fitting

 

I was planning on booking a power run at Surrey rolling road to find out what it's running I might take a risk and fit the Nur Spec R and hope it's ok, if not I will have to fit the old one back on and book another power run
