Specs: Z6 head and B7 block, Z6 timing belt, Z6 Dizzy, Skunk2 Intake mani b20 throttle body and map sensor. FPR and fuel rail (running 50psi fuel at idle). Converted P06 ecu with XS chip. **I was just wondering if with a chipped ECU should I bother using a VAFC?** **Lemme know your guys experiances and tips** ---

if you have a chipped ecu you should tune with that and a wideband o2 sensor (borrow a friends if they have one, and a laptop/eprom burner) thats way better than using an AFC, far more control, generally better results if you know what you are doing. ---
