GM crate ls3 very rich

I have the 525 hp crate ls3, harness andecu pakage from the Gm performance boys. It seems to run very rich and I'm wondering which tuner you all would recommend for this, I'm thinking hptuners but admittedly do not have much knowledge on the subject. I want something that will work with future head and cam mods.

The GMPP tunes tend to be pretty close. Before running out and looking for a tuner I would make sure your installation is good. Are there any leaks in the exhaust before the O2 sensors? Is the MAF installed per the GMPP instructions?

And are the O2's on the correct sides?
