can it be done, and is that all that i can get?

 

300 more hp can be done. If you can afford it. What are you looking at doing to get that gain? About the only way to nail a 30hp gain, besides a 30-shot of nitrous, is to do a 3.0 stroker build. You can supercharge for a roughly 100hp gain. You can build the internals, use custom turbos, and all kinds of **** and make 1000hp or more.

It's all about money. Your question is too open-ended to answer.

 

I checked out some ecu software, along with intake and exhaust. It basically added up to 30hp. But i want more. Eaton has a supercharger, but for 4k, it will have to wait a year. Just looking for stuff i can do now to raise the output.

 

No it doesn't. The reflash will net you 4-6hp max (although a 15ft-lb torque gain in the midrange is definitely believable). Intake will gain basically nothing but sound - the OEM system can far outflow what the engine demands. Ditto the exhaust - couple hp way up high is the best you can hope for. If you want to mod for power, you bought the wrong engine.
