Most people dyno around 400 to 410 rwhp with LT headers and a CAI, about a 30 to 40 hp gain. The TB won't increase your hp but it will increase throttle response.

Depending on which headers and CAI I would say the 30-40 rwhp range Enduring mentioned is entirely reasonable.

Mods and dyno results in sig.
Yours might be a bit higher as 2013+ have electric power steering.

Around 400rwhp. Just a number. My old 4th gen Camaro was pushing low dyno numbers and killing a lot of 'higher rwhp car'.

We usually see about 50+ WHP gains with our stage II package. (KOOKS long tube headers with cats, Roto-Fab CAI, VMAX 90mm CNC ported throttle body, Elite Engineering PCV catch-can, JDP/Taylor wires and TR55IX spark plugs.
Here's a dyno sheet from one we did not too long ago:  Feel free to call, PM or email me anytime with questions. Best regards, Tyler 888-308-6007 |
