Just wondering in my case,is it possible to put stage 2 cams (for example skunk 2 stage 2)? Cause all my internal is stock. Also I have a question,I'm thinking to buy AEM UEGO air/fuel ratio and VAFC2 (cause to hondata or other similar,here) to fine tune it.Do this will make a noticeable different or the stock ECU just good enough? Thanks.
