you should not trip P2096 cel code its a real code and indicates lean condition


Is 02 spacer in the REAR 02 sensor, never put spacer in front 02 sensor.


could be leak
incorrectly installed front 02 sensor


use you mates OFT log


AFR
commanded AFR
LTFT (long term fuel trim)


If you have high positive LTFT and the AFR is leaner than Commanded AFR at low to medium RPM , but ok at higher rpm then you almost certainly have a leak at haskets joints or cracked header or incorrectly installed 02 sensor, they must screw in in all the way till ring is tight.


Use a thread chaser to clean up header threads if necessary


The code you thow for catless header is P0420 cat efficiency, this is the only code you should disable on NA tunes unless your running flex kits into rear o2.

Thanks for the info and instructions! We'll plug it into the OFT and check for a leak later today when I'm at his garage.
