Im betting that with H/C they are probably over 100%. I had mine at 112% with H/C on my HOSS before a local shop rejetted them for me. Basically into a 36#'r.

I just had an LS6 dropped in with a custom cam and mine are running at 107%. I know I need to have the injectors upgraded and my installer/tuner said they SHOULD be upgraded, but it's not MANDATORY unless I'm going to be upgrading the LS6 intake to say a FAST... any thoughts? Also, as far as buying injectors with the idea of "room to grow" is there such a thing as getting injectors that are too much?

IMHO, there are a couple things you should NEVER skimp on or push unless your ready to spend some money:

Fuel system - Too lean OR rich, and your walking and it can happen FAST!
Torque converter - You cheap out, and get a **** stall, it can and will take your trans with it.
Valve springs - A dropped valve is a day ender.. Ask me how i know.
