197/297 O2 sensor problems

I installed a Vortec supercharger,BBK long tube headers, BBk high flow cats, have a Brenspeed tune. Problem is I keep getting fault codes for both side O2 sensors saying there is a lean issue. I did add extensions to O2 sensors to move them out farther from exhaust flow. Anyone have any thoughts?

Hmmm I would think this mod should have included bigger fuel injectors and fuel pump

Get ahold of Miles in our tuning department. He can be reached at [email protected] . He will be more than happy to take a look at the tune for you or give you some things to troubleshoot.
