JB4 not working well for me real world. I'm seeing 14.2:1 AFR's under full boost and higher rpm. I'm also seeing 15.8:1 spikes regularly during spool. I'm not comfortable with it at this time. I messed with the settings some but it needs a O2 biaser like the N54. |
A.J., It runs the same AFRs as the stock tune does. It doesn't run any leaner. If the AFR was that far off the car would be throwing codes left and right. I've yet to see a single code get thrown on mine.
