Boosting my 543,000 mile Yaris

As for the fuel pressure you want the pressure to rise 1:1 normally so in otherwords 1psi of pressure for 1lb of boost. Since the stock fuel pump has a built in regulator the only way around it without doing a fuel system upgrade is to have the stock FPR modified to allow more flow. Most folks half ass it by putting in even bigger injectors to overcome the stock FPR. Scott and I have done extensive research and testing on the stock fuel system much of our findings are noted on my build threads.
