+1id ditch the bullydog and get a diablo
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.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.
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.
