They dont really update their website so it seems... you will find it on their facebook page. I know they did dyno tests and stated 20RWHP.

Much better bargain to get a flex fuel sensor and tune, most guys see 60-80rwhp gains without increasing boost.

I have the NX lid looks bad ass and whine is louder. Performance wise is has to help. The inside is much smoother and ported edges. Expensive...yes..worth it IMO yes
