Try raising the fuel pressure 1/2 psi then test, keep doing that till you get the best perfomance.
Do the same with the timing, increasing it 2 degrees til you get the best performance, you might have to use a higher octane of fuel.
Disconnect the vacuum hose to the air cleaner flap, you want max air flow there.
