I had an LT4 fuel system on order from Summit and was going to send mine to CSP for tuning, but I sold it and went C6Z instead.

Retune and picked up a bunch of power. I almost bought a C6Z before a 6th gen. I had found a black 2007 with 7k miles. I couldn't reach an agreement with the dealer on fixing the heads as a preventative.
