It will not hurt performance, get it custom tuned.would running a prl race maf on fbo and a stock turbo hurt its performance over the street version?
Sounds about rightI never got it tuned when it was street maf, but its now (i thought I was gonna go upgrade turbo upgrade that's why I got the race maf) custom dyno tuned with race maf. tuned and got 370hp with 93octane.
