anyone use a cortex tuner on their f-body? Soo my dad has a cortex tuner he uses on his duramax, and i was wondering if anyone has used it on their f bodies and noticed any actual power gains? I have a m6, so im not gonna be gaining any shift improvements, but i am curious as to the power gains. P.s. its going on a 2001 ws6
