[baby huie]

ok i was wondering do i need a fpr even tho i have dsm link i aqm in the process of getting my car back together and i got 680 injectors and a 255high flow fuel pump going in should i buy a fpr or is it not needed with dsm link cause u can tune it.

yes get an fpr, you can alter low fuel trims with a dsm link, but an fpr gives you an actuall way to adjust your psi, your 255 will overrun your stock fpr at idle.

aeromotive fprs are among the favorites.

I have 680's and a 255pump. I still dont have an afpr but I did not see any bad side effects without one.

As was stated, the need for an AFPR does not depend on whether you have DSMLink. You can't adjust fuel pressure with DSMLink. And most likely a 255HP will overrun your stock FPR, although that's not a hard and fast rule. Like the above poster said, some people don't have problems, although most do seem to.
