Blue Spring Upgrade

Just wanted to see what kind of fuel pressure you guys are getting after the blue spring upgrade. I havn't changed mine yet and stock I run 58psi at idle and 50 psi at 2800 rpm's.

Blue spring will get you closer to 65 lbs Really doesnt effect performance but good cheap insurance that it wont get below 45lbs which your getting close at 2800rpms. What is it at wot?

Typically 60 - 67 psi....every truck is different.

Mine runs about 62 idling......56 or so at WOT.

Since you are right at the edge, it would be a great idea to put in the upgraded spring.
