Hey everyone! Just installed the greddy turbo kit on my 3sge beams altezza. In the beginning it was just around 0.3 bar.. everything was fine. Recently I've lowered the compression and boosted to around 0.5, 0.6 bar..
Here's the thing.. I have stock fuel pump, and stock ECU. While accellerating, whenever I press the throttle gently, and increase the throttle as it accelerates, it does pretty well.. but whenever I'm going full throttle, it doesn't.. I can see the turbo going up to like 0.5 bar, but it doesn't accelerate normally whenever I fully press the throttle..
What could be the problem? Is it just the fuel pump, or I should buy another 500$ remapped ecu as well?
Thanks in advance!

Are you trying to fix it cheaply, or properly?

Cheaply: adjustable FPR and wind 5psi more into the base fuel pressure
Cheapish: Walbro 255, SAFC and add more fuel yourself
Average: Walbro 255, SAFC set on a dyno
Slightly more exy: Walbro 255, remapped ECU
Properly: Walbro 255, bigger injectors, remapped ECU
