Does anyone know how much the stock injectors/fuel pump can handle with a twin turbo kit before needing to upgrade the fuel system?

Ive searched and couldnt really find a direct answer. Hoping someone with some knowledge could chime in.

I have a TT setup that I am about to install but Im not looking to push crazy numbers. Just something a little under 400whp or at 400whp. Could the stock injectors/fuel pump get me there?

 

Anyone? I know the stock pump has a psi of 52ish

 

Not without increasing the voltage to the pump and modifications as specified in the JWT TT kit. You can download the install PDF from their site to see what you need to do if you really want to stick with a returnless (stock) setup.
