    04 GTO Diablo Tuner SES L/R Bank to Rich

    I have an 04 GTO with K&N CAI and Granatelli MAF. I bought a Diablo tuner and have used their default tune that comes with the unit. I keep getting a SES code for Left and Right bank too rich. I have not got into the custom tuning option of the unit. Can I lean out the fuel mixture without making any other changes, ie timing? Also, what is a good percentage change to start with when adjusting the fuel curves and which one (low RPM or high RPM table)?

    Thanks

    Just guessing - sounds like the their tune doesn't like the GMAF???? I'd try putting the stock MAF back in.

    I tried that and put the tune back to stock. Would the K&N CAI trip those two codes?

    Stock tune and stock MAF and still throwing the rich codes? If so, something else might be going on. I'd post the actual codes so someone more knowledgeable than me and possibly help. I have FTRA and K&N filter on my car, never threw any codes before or after using the Predator base, or custom tune with the stock MAF.
