05 Mustang GT Mods

[danaconda]

I have an 05 Mustang GT. I have the C & L cold air intake installed, with the Predator custom tune. I'm thinking of upgrading to an aftermarket axle-back exhaust, along with an underdrive pully kit, and a 3.73 gear.

I understand I can change the parameters for the gear change with the Predator, but will any of the other mods require a custom tune? Or better put, would it benefit me in anyway to have a custom tune done after the mods anyway? Thanks for your help.

Those mods should not require any mods to your custom tune, you should be good with the tune you have now for that.
