After exhaust is filter and larger throttek

[Burger Prince]

My 2006 coupe set up includes headers, high flow cats and exhaust ... Running stock filters and throttle body. Ads say these 2 modes will will complement the add ons I have. ( air in air out) 13-15hp each? thinking of the green dry filters and the larger throttle body. (herd oil soaked filters are bad like k&n ... Waste??? Or will this really open her up and give seat of pants power? I've herd both? Would I need to retune after or will computer compensate??? Great mods or a total waste...
Thanks

I wouldn't expect those advertised gains to hold up or translate to a real SOTP difference, but collectively with other mods... they can help. If you've not had the car tuned, I would suggest that. Probably not seeing the power from your existing mods until you get it tuned.

+1 on the tune. I did cat-back exhaust, cat delete pipe, green air filters and didn't really feel a difference. A couple months later I did a SCT tuner and it really settled the car down. Much smoother and it gets rid of that stupid skip shift light.
