Fuel Pressure Mod?

What exactly is this mod? I've searched but no luck! What are some of the advantages of it?

It's not really worth the time. Get a RR system.

Ok well i put on a guage on the truck and i see 60psi at idle and when i get WOT it goes down to 25 pounds. Its weird the truck doesnt fall off when the pressure drops. Now i ran the truck on diesel and my Bio mix and i have the same results. Any Ideas? DO i have to bleed any air out of the gauge line? Could it be air in the line causing the drop in pressure?

Would the REG Mod fix this?

if you're running a hot tune, it's simply that the stock fuel system can't keep up with the demand the tuner is calling for...

time for for a FASS150/180....

run it with stock tuning and watch the fuel pressure...if you're still seeing a big drop, then check your fuel filters to see how dirty they are....if they're good, your FP may be getting weak...
