Overall a good little unit....mounts easily on the steering column out of the way....only gripe is i wish the cable was on the left side of the unit to facilitate mounting on the dash near the pillar.....pretty easy to install...i was able to do it and i cant walk becasue of a knee problem....

On my truck with Beta 4.4 (Level 7):

Idle FP = 8-9psi
Lowest PSI reached (didnt floor it, but did get on it): 4 psi

Idle Rail = 9k
Max Rail = 25k

I would purchase this product again....great price point and good functionality!!! Happy i was able to purchase something from Quad as his participation on this site / customer service is great!

 

In your sig you say that you have a GDP-392 fuel system installed. If you see that low of fuel pressures it sounds like something is wrong. You should be in the 20+ psi range at idle and even up to 42 psi with the bypass valve tuned.....

 

I noticed the same thing. Those pressures look really low for a GDP system. They look about the same as stock...is your GDP pump installed yet?

 

That was also the first reaction for me, low FP. I like it but I put some flat black over the last couple inches of wire so it would hide it from being seen. I mounted mine right above the steering column.

 

Sorry guys, updated my sig 2 days ago....pump goes in on saturday.....my bad, appologies for the confusion.....
