The injector pump would be the best alternative. You would need to find injector shop that can upgrade the pump to put out more fuel. The pump and the injector nozzles would be upgraded for more fuel output, this will get you the added horsepower, it will also get you more smoke! Dealer is not going to be any help, unless you want them to remove the parts, they will send pump out themselves , to an injector shop. You won't find any bolt on performance parts for the tractor. Adding a turbo charger is much more involved, as it requires injector pump, injectors, and new manifolds and different pistons, as well as turbo.
