All I have for the engine so far is a short ram intake, high flow cat, catback exhaust, and i got a BBK High Volume Fuel Pump as a gift ($150 bucks) ...

Is this going to give me any more power/torque?

Is it going to lower my fuel economy (significantly) and not really offer me much benefit?

I'm fine with not installing it, so if it's not worth sacrificing a good fuel economy for, then I'll just sell it or something.

Thank you very much to anyone that can help.
