Hey guys just installed the fast intentions rhfc, on top of that I have a z tube (g35) k&n drop in filter, muffler delete and plenum spacer. My concern is that I am running lean and it will cause damage to the engine over the long term, Car runs great,I do not have a check engine light. Do I need a tune asap?

I would get an UpREV tune.

Maybe a BBK for some bling while you're at it.

No, you will never cause engine damage from those mods alone. A tune might get you 10 ponnies, but it's not necessary
