Welcome, Some of your terms are not what I'm use to seeing. Like
the exhaust Injen air box ,Bully dog tunner, but if that's like a CAI, exhaust and a performance tune than without going into the engine, adding a blower, turbo or NOX you might be out of luck.

You can change the throttle body and injectors but with a 2010 I would think you would worry about what your warranty will cover after that. You can add headers but they don't usually add that many ponies.

throttle body, headers, underdrive pulley will all add a few HP each. Beyond that you will be looking at heads/cam, nitrous or super/turbochargers

I would avoid the 90mm TB. No real benefit if you can't port match the 5.7L intake manifold. I second the Diablo Predator or Trinity purchase.

best thing you could do at this point is headers. I didn't know there was a bully dog tuner for these cars. i am itching to stab a cam in mine, but it will probably be later this summer after i finish all my other gazillion projects...

yeah, the larger throttle body works really well when mated with a port matched intake manifold, but only when accenting a larger cam. The throttle body upgrade alone would be more time and effort than its worth.

Long Tubes and Cat-Less mids with proper tune was worth 44 RWHP....Id say that is your biggest bang without a power adder or tearing heads/.cam off.

Doug Thorley Headers....they are technically for the SRT. But they match up perfect for the R/T
