I don't think simply adding more fuel will help this motor unfortunately... it's got a lot of head work, a lot of compression and a big ass cam based on a Bathurst GTR XU1 cam. The maps need a complete going over, but the guy can't afford aftermarket management at the moment. I remember someone on the list saying they had the instructions to install a custom written eprom, just can't remember who it was.
