i am reading between 720 and 800
i thought, i should be around 875.
i just put in new gnx o2, fp 44psi, with 110 race gas
any thoughts ????

875 is rich.
I think 780 is the magic number.

topfuel is right on. 800-820 is rich, but is a safe rich if your not trying to squeeze every little bit of power out.
I like better safe than sorry and my car also isn't for all out race....mainly a grocery getter
