Not sure why the 02's are an issue on the Doc Race setup but I'm sure one of you knows:

So, you bring this up and you get kicked out of the group? Yeah... that's not a solution.
Plenty of people confirming the problem:
I have had non stop 02 issues with this kit as well, tried everything. Barley drive the car now because Im sick of changing 02 sensors.
Kirk Dorr yall need to send updated manifold to people that have non stop problems, people paid so much money to go ST and then this happens
I remember having to sell my car after I switched from on3 to doc race ST. J.R. Boyd can testify. We even tried relocating the 02 bungs that didnt help. Overall docrace already left a bad taste in my mouth never ever going to run any of their kits
