Sadly, I do not have before or after anythings for the throttle body. I have dynographs before and after the ACE setup though, but the before includes the throttle body and CAI.

jailiu.jiayu: better other way around for more gains. Catless header and catted frontpipe. Primary cat in headers hurt performance more due it's placement near cylinders, and also need to put it there hurts header design, striking out more efficient. One can also save some $ with catless header and eg. "free" stock catted frontpipe.

i cant ignore those sign on dash........

will do more research

and i need find some local shop first for tuning too

jayliu.jiayu: Signs on dash? As in check engine light? But you also wrote that you plan to get ecu tune aswell. Disable cat readiness checks in it (in most ecu tunes it already is done), should do. Aftermarket catted header btw is not sure way to never throw cat related CEL code. So most probably you'll have those checks disabled in tune for it anyway .. and if so .. why not catless header in first place?
