Just wondering what kind of gains people have been able to obtain from porting the stock, dual-stage H22A intake manifold. I'm going back to the dyno in a few weeks, and wondering if I should do it before I head back or worth the $200 or so.

 

I see you have cams, CAI, and a header... It'll help, a tiny bit.

 

only a tiny bit?
it could make 3-5whp, no?

 

why port a stock manifold..it's a POS...get a euro0r or something
