Alright, here's the deal. Installed LT header (catless OBX) Did all the part throttle stuff and right now when I log, I see the STFTs all at 0 to -2... I installed a PLX DM-6 with the Bosch WB sensor and it reads 16.3 through 17 normal driving... When I do go WOT it comes down to 14.7 to 15.5... WAY TOO LEAN! I turned on LTFTs just to see where they were nd they were at +7... If I go into HP tuners and force open loop my WB does not change! AT ALL!!! I've tested the sensor according to the PLX install instructions... all seems good there... I've checked the ground on the unit and verified power is at 12.8V... Any suggestions? Is my car really running that lean? Is there a problem with the WB sensor?
