So i just recently installed my 550cc injectors and the lexus afm, already have a walboro 255, no AFPR. Anyways, i turned the boost up to 15 it was all good yadadada, driving home on the freeway i got on it... 10 psi. Wtf? Got off the freeway, went at it from a light, 10 psi... ?? I AM ON STOCK BOV! Think the 15 psi was just too much and it opens a little letting some past? My boost gauge shows no vac leaks, -19 at idle. Entirely clueless... please help me out!
