advise on fuel pressure regulator setting
Hi bros,

I need advise in fpr setting for evo 3, im using walbro fuel pump with stock ecu n injectors, my foreman set the fpr to 3.5 bar with the vacumm line on, but car feels really heavy, and with aircond on its even worse, today I reduced the fpr to 2.9bar on idle with the vacumm line on. Any recommendation for ideal setting for the fpr. Tq
