So I added 5/16 MD spacer, Headers, And HFC the other day. I already had INJEN Tit exhaust and pop charger On 2004 coupe NonUprev. So I'm wondering what would my options be right now as far as tuning goes other then having to get it Dyno'd? I been read a lot about Osiris tuning but all for UPREV motors only. Can anyone give me in site on this or is there anything more I can do?

You mean non revup. Anyway, yes you can still get an osiris tune on your car.

Maybe a crank pully to free up some power.

since you're non-rev, you'll need cams to get anything worthwhile out of those headers

If you don't want to go the standalone route an Osiris reflash is definitely worth the money...
