if i added a walbro fuel pump on a stock fuel system would i be able to hold a lil more..????

 

a lil more what, boost?? kinda but you will also need injectors and a controller, if you are going to be getting a s2 kit then you will be able to hold boost to a high psi. but stock 16 is the max even with a fuel pump maybe 18psi, I have my w/g set to 15 and mbc set to 18 but holding 16.
