Hi,

I've recieved a stage 3 chip from PTS Motoring , 3 BAR Map , Greens, and RS 500 Cooler.
The boost was recomendet at 22PSI and when I have checked the AFR it was over 14 , so turn the boost back to 1.2 bar (and have now 12,5 AFR).

Please Post your AFR's for more information is it normal to drive with 12.5 AFR , because that wath i hear is under 12 on high RPM, the injectors are brand new the fuel pump is OK , what could be the reason for going lean.
Please Help
