So your still running the stock lt2 manifold and stock TB. Pretty impressive I'd say.

I don’t suggest a MSD for a bolt on car not enough gains over a LT2 to justify the cost IMO. I know on the C7 you can’t run the LT2 manifold but I highly recommend a LT2 manifold on a 6 gen if you plan on just staying bolt ons. I got mine from GPI. With that $800-900 price difference I’d get a set of longtubes.
