hallo zth,
i need help here, ive change back to std td05h turbo 4 months before,
last week go for tuning to adjust everyting,air flow,ignition timing,and boost pressure as i feel im wasting the fuel and the car running not that smoothly.
so when i dyno, the tuner realized that my fuel pump is not supporting enough fuel, my fuel pressure meter drop when my car start boosting to 1bar.so they decrease to 0.8bar.
now they ask me to upgrade the fuel pump, currently im using walbro l255.
previously im using gt30 turbine and i never come across this issue.
so guys, what should i do now? replace the new fuel pump or can i use 2 fuel pum at one time?im planning to put merz external pum, is it possible to do it?
fyi, im using evo 3 engine.
