Hi Todd. Good to hear from you. Actually its the left bank(Driver) that is on the lean side. The discrepancy is greater between the two banks at slower engine speeds. At higher rpms, tends to straddle 128 BLM +-2-3 with copious tuning.

Earlier I had a real issue which turned out to be defective secondary injectors.
FIC quickly replaced them gratis. Switched those out along w a new set of coils.
