AFR Condition

[amm]

Hello Guys .. My car (2008 GT Mustang) is upgradded with the Steeda CAI, Diablosport Steeda Canned tune and the High flow Steeda elbow tube pipe, Also Magnaflow Axle back mufflers. Now I have the Underdrive Steeda pulleys and Magnaflow catted X pipe and I'm planning to install them as soon as possible. The point is about the Air/Fuel ratio, are those additions upgrades need a custom tune or will hurt my AFR (Lean Condition) or car Safe everyday drivability or am I ok with the Steeda tune. I'd like to listen from you guys and thanks a lot.

No, you wont need a tune for either of those mods, the Steeda tune should work fine.
