I had a PLX.. I've bought mine a while back so it may be different than the current ones. My PLX worked fine for WOT tuning but always read around 1 full AFR lean whenever the PCM commanded 14.7 AFR. basically PCM commanded 14.7 PLX would read 15.6 AFR. It caused the LTFT's to be off quite a lot when I was using the WB to sim the NB and was just generally annoying seeing it off in logs. After I got LT headers I went back to NB's for the PCM and tested the PLX vs an LC1 by installing one in each bank of the car and found the LC1 to be accurate. Again though this was probably 2 years ago so they are probably different now.
