Ford mustang upgrade tips. CAI or shorty headers?

I have a 2011 v6 mustang and would like to improve the HP/torque what would be a better first tune?

Take your pick. Neither makes enough difference to notice…

They will drop the resale value of the car significantly though.

Put a racing stipe on it.

Both will offer small gains and really should be used with other mods. But I guess you could go with a CAI as it is easier to install. The most effective power adder you could get is a supercharger or turbo setup followed up by a NOS system (but it ain't very practical for everyday use).

Hi so the stage 1 cam is the usual first upgrade most would make.

Ca1 is more effective but remapping us best option of most situations for power for bucks as an initial change. Ideally using a combined approach and getting to result we want may be better still rather than doing small changes that we won't really notice much difference. Do be aware insurance company needs to be aware of changes ( or invalid cover) plus resale values can drastically fall unless find a willing buyer in a limited market.
