I have mugen headers, K&M intake, and berk tech header back. Just wondering how much power I'd be pushing out and if I did get a tune how much more I would be getting. Thanks!

 

18.7122 whp
13.8771 tq

give or take

 

my calculations say 17.9671whp but it could just be the elevation

 

13.7 jiggawatts!

 

I recommend searching through the dyno numbers sticky HERE. You will find every bolt on combo in there somewhere. This was your first post and from now on you should search first because i can guarantee every one of your questions has been covered before. And a little fyi our s2000 has only one "header." Singular not plural...
