Really? What motor, altitude and temp? Those are huge jets.
Its a 10cub cameron did. Im around 500-900ft elevation, and temps vary from 50s to 90+. For some reason i always run bigger jets then most. Im not trying to say i have the "perfect" tune, but the hills we climb are long, steep, and soft. It puts alot of load on the motors. Imo, i personally think more fuel is better when loading a motor very hard. Once again, im not saying im right, im just sharing my opinion.
