after header afr?
I just installed a pair of long tubes a ls6 intake, a lid new air filter and new plugs and wires, and new 02 sensors for the front, my question is without a tune I had around 16:1 at idle but when I get on it a little I get around 14 or 15 is this normal? And is it safe to drive on, just bolt ons car, stock internals
