Well, you could try a nitrous system. But that is very short term. You're going to have to get more fuel and more air into the engine and open up the exhaust system to get more air out. Get an engine programmer (available after market) to fine tune the fuel/air system. Installed tuned headers, and an opened up exhaust system to let the increased air out.
