The injection system is fine. I would install new injectors and make sure there are no vacuum leaks. Set the lambda up on the rich side. This will help when on full throttle contact. The only other thing is ignition timing. There are many different timing maps for different ezls. I would probably suggest a stand alone ignition module for getting a tuning map. Getting timing up into the 22-24 degree range at top end really wakes these up. Also if you are looking for top end power the exhaust is pretty restrictive. New headers and down pipes and catalyst. Get rid of the resonator and new muffler. Better air filter box also.
