^ its easier to tune and with those parts when or if he chooses to up the boost he can do it without maxing the fuel pump and etc out.
the stock fuel pump is like 70 where as walboro is either 190 or 255
even on mistajuices NA gsr build he needed to upgrade the fuel pump to get a really good tune and make more hp.
