My wira 4g93t with evo3 air flow sensor, td05 turbo, 510cc, evo3 rechip ecu for 2 bar, afr, 255l fuel pump. All inside/outside upgraded. Run smoothly for a year. I set max for 1.2 bar boost only. Last 3 days ago...
need to ask sum question here, my 63T originally was used 1.8 fuelpump from gti, boosting at 0.75bar ...and i just change my fuelpump to walbro 255LPH fuelpump...after fixed,tested the car....the boost suddenly goes...
