Just wanted to share a fix to an issue I had. Car would get terribly lean when boost was ramping up, in my case 3800-4000 rpm. AFR's went to 19 for that moment, not good at 20+ psi!! I'm using the stock rail and had an Aeromotive FPR mounted to the passenger side front fender of the engine compartment, with 2.5 feet of vacuum tube to it. Took me a while to find the solution and it was in part due to a post I read, can't recall who it was, who had the same issue but never fixed it technically. He happened to replace his stock rail with a Perrin and it fixed his issue. All this got me
