I don't want to sound mean, but do you know what's needed for a turbo system?

With a turbo, you need a way to add more fuel. One way, and its not the recommended way, is with a rrfpr. This raises the fuel pressure and allows your stock injectors to dump more fuel than they would at stock fuel pressures. This should only be used for low boost applications as eventually you completely max out the injectors.

The other way is to buy bigger injectors. But you need a piggyback, standalone, etc. to be able to control the larger injectors and tune the car properly.

Both of these require a larger fuel pump to be keep up with the extra demand. Which you already have, which is good.

However, from what you have said, all you have right now is a larger fuel pump and nothing else for fueling. So I'm not surprised at all that you have problems.
