it'll definitely help but if the seals on your pump/rack are already shot from the thick fluid then adding the right fluid isn't gonna save you

 

Ok first off, are you running a GIAC K04 tune or a GIAC K03 tune?

To me it sounds like your running a K03 tune since your only pushing 15psi, if so then there is no way in hell your going to have enough fuel for 22psi on a K04. Most of the K04 tunes run 18-22psi already and need a 5 bar fpr (4 bar is stock) with the stock injectors or run larger injectors with a 3 bar fpr since lower fuel pressure means more flow from the pump.

 

i have k04 tune

 

What year is your car? Because the GIAC tunes usually run more then 15psi.

If you have the 5 bar fpr or the 310cc/3bar fpr combo tune then you will be just fine turning up the boost to 22psi. Just make sure you log the car to make sure it is not pulling too much timing or running lean at WOT.


If it is more power you want have you looked into see if GIAC has a race program for your car and for the switcher they offer?

 

its a 98
