First time with the WB wired up to ecutek, it posted CEL P0452, P1449, P0453. These were later disabled in the tune by the tuner and now it post P0451 intermittently. Got another tuned with it disabled. will report if that fixed my issues. Has anyone got any of these issues or have any ideas for solutions?
More than likely ill just undo all my wiring since its messing with an important piece of my setup.
any help would be appreciated.

I'd probably recommend undoing it and connecting the wideband into the O2 sensor input instead. PTuning EBCS uses the EVAP wiring to work (from what I can see in the install manual), and for Ecutek, it uses the EVAP/CPC signal to control boost IIRC. When tapped into the EVAP signal and attempt to use it for wideband reading, you essentially disabled your ebcs. All the CEL codes that popped up were for your EVAP (or in this case, probably the connection to your ebcs). Ecutek has an option to use the rear O2 sensor as an input for wideband instead of the EVAP/CPC signal IIRC.
Might also want to try putting this in the forced induction section.
If anyone else thinks I am wrong, please correct with proper info.
