If i install a higher flow fuel pump is that all i need to run about 15-16 pounds of boost? or will i need to get a tuner, injectors... thanks
 
You should be abel to get that out of your stock set up with free mods and a mbc unless you are hiting fuel cut? If you go higher than a 190 you will need a fuel pressure regulator that raises your fuel pressure at a 1:1 ratio under boost.

What he said.

If you go higher than 190 you may also want to look into tuning (Palm/logger/safc ect.) so you can tune down your fuel pump so it doesn't overflow your stock injectors.
 
If you are running 93 octane you can upgrade just the fuel pump to run 15-16psi. You will also need a mcb. A 190 will be fine for you, and I would get a logger, its 105$ for a logger on www.obdloggers.com so you can monitor knock.

You can probably run 15 or so safely on your stock system but id recommend getting a logger before anything. When you want to run over what is safe on the stock fuel system just buy bigger injectors and fuel pump (at the same time is your best choice imo) Along with an AFC or other standalone to control your air to fuel ratio.
