B&M FPR walbro 255hp with boost?? did search did not find def answer..
 

i hear that b&m fpr with a 255 walbro hp fuel pump is a bad combo since it wont allow you to lower your psi below 40.. is this true.. or a rumor.. please someone who has experience give some info and not someone with mere speculation..

i could not lower it below like 45 psi at idle with that combo.. but u can drill a small hole in the stock regulators return port to drop it back down . thats what i did and its worked great ever since..there is a link on here somewhere .

yeah use the stock unmolested reg, or go with an external like an aeromotive.
