C6 owner with a LS3 which of course does not have many miles on it.

This is what you get when adding so called mods that cyberspace "for profit" forums lead you to vendors who do not know or even care on what they are doing

Heads and CAM, blown engine within a few months, add the crap tune done and you see how much carbon pistons have and valves kissing them along with broken lifters.

They totally missed the tune if it was that rich and timing so off they kissed the pistons. I looks like the tune was rich enough to run a supercharger.

Yep, I agree.

It is interesting that GM uses a 48 lb/hr injector for the 640 HP LS9 for the ZR1 and vendors con owners into 60 lb/hr injectors for nothing more then CAM and head work.

Worse is the PCM for C6s do not allow large injectors to be used since they limited the injector flow table.

Making it worse when buying such products and services from a vendor in another state makes it real hard to sue their asses when the end results are like this with no engine warranty.
