Hey members. Installed headers with true duals. Deleted the AIR and EGR. Car is running great. My question is will I damage the engine running as is without a tune? Will I gain a substantial amount of HP and TQ with a tune? Thanks for your input.

you will get the most out of your headers and duals with a tune. The chances of you damaging anything is really slim (if that).. get a tune unless you have some other mods coming up in the near future
