Getting the last of my stuff today from AMS , and I wanted to know what things I need to be worried about with upping the boost. I am only going to be running 18-19.5, not over that. Should I go ahead and spend the coin to up the fuel pump, or would it not matter without doing the injectors.

 

What exactly are you getting? As an example, 18-19psi on the OEM turbo and 18-19 on some T3/T4 varient is two completely different things.

 

Sorry, I did the Stage 1 from AMS, no turbo upgrade. I will be running the stock core, just SAFC2, Boost controller, cat-back, no down pipe, etc.

 

It can't hurt to have the fuel pump, but it isn't really needed at this point.
