Hi All,

I just installed a VF Engineering Supercharger kit in my 98 2.8L BMW Z3. I am getting a CEL with DTC 1188 - fuel control (Bank 1 Sensor 1). The LT and ST fuel trims indicate a lean condition (LTFT = 11.70) and STFT up around 15). Has anyone experinced this with the VF Kits or have any idea what could be wrong?
