ok so i just installed a airdog Raptor lift on my 02 cummins took it out for a spin and my low fuel pressure light on the dash still comes on when u get to top end . the pump is preset at 14-16 psi from the factory is that not enough fuel pressure? all i have on the truck is a edge comp box. any ideas or suggestions?

 

I'd be verifying the fuel pressure with a mechanical gauge before any more hot rodding.

 

What light do have?

X2 on using a known good gauge and keep your foot out of it untill you know for sure.

 

I don't think I have a light
