    Set P0121 Min to 0 and max to 100 but still getting code

    My basic set up is 6,035 feet above sea level, 99 Trans Am, Automatic 60lb injectors, 255lph fuel pump, LS6 intake, P1SC Intercooled, trans cooler, polly motor/trans mounts, sway bars, subframe connectors, 3" true dual exhaust.

    PCM rationality test ie p0121 is set to Min of 0 and Max to 100 but I am still getting the code. Is there another table that I should be looking at? Only other code I get is the P0742. The Car runs great and is having no other real issues. Thanks for your help.

    Set Max to 105. If you still get it, set the 0121 code in the DTC editor to option #3
