I was under the impression that the stock one was good for big power unless it was broken; might be unessasary at your level of tune. Although the Tomei one along with the gauge looks great in the engine bay :D

The trouble with the stock one is it is not adjustable, when you upgrade fuel pump and injectors you wont be able to increase flow rate pressure

Fair one but generally most people set them to 3 bar (without vacuum) and leave them at that. I was told by my tuner that I should have just kept the stock one as it would have done the same thing as the Tomei one I use now.
