ok i have a 2000 gti 1.8t and i have intake exhuast n75 ground kit 4 bar boost controler and a forged motorsports diverter valve. it is the diaphram type so it comes with 3 springs with different strengths. when i use the green spring (weakest) my car runs fine but its not loud and doesnt hold boost well. when i run the blue or the yellow spring it causes my car to go into limp mode and only runs 5 lbs and i loose the signal from my n75. if anyone has a in the cab mbc they here the same clicking noise. i just need to know what could cause this problem and if anyone has expierenced it before
thanks
