Thans for your input

1) Try and do logs with the OEM Bosch plugs. Don't waste money if not needed. Mine was doing fine with Stage 2+ and OEM plugs.
2) Do not check the OEM Catted Downpipe checkbox then you won't get emission light.
3) Check cold start delete checkbox to quiet down start up plus it's useless since you have no catalytic converter.
4) I don't know how good the fuel is in your country, but if the octane rating is not reliable I'd start with one grade lower to be safe. Do logs and check for Ign timing corrections. Move up one octane rating if safe to do so.
