My bike is out of fuel at 230hp..I am installing rc engineering 380cc injectors along w/high volume pump & regulator...Question is should I connect vacuum to the regulator to lower pressure at idle or just try to map at constant 42psi?..I almost would like to have it constant, seems like one less thing to act erratic & f. up my mapping?
