Ported Intake Plenum with Stock Cam
Hello Corvette Forum! Long time reader, first time poster here.
I have a 2012 GS A6. Only upgrades are 2" Speed Engineering Headers, 3" SE x-pipe & 3" SE true duals. Before I get my tune I was going to port, polish & rail my factory ls3 plenum because it's almost a "free" mod.
Am I wasting my time doing this with a stock cam and intake?

No not at all. Just don't get so aggressive to make it worse rather than better. Stick to cleaning up seams rough areas etc. Watch a you tube always good. There are places that port stock manifold, edgy vette comes to mind.
