I noticed that my boost is only going up to 14.5-15lb or so, with my GIAC X... How about you guy's? I think I should be over 15lb, maybe 17-18 at most... I'm going to go through the usually checks this week... DVs, TBB, and MAF. I'll also do some boost graphs and MAF charting.

Dealer said last time I was in the getting some warranty work done, that one of my Forge valves might have a problem. So I'm going to start there...

I'm going to check my DVs when I get home tonight. Do you what what I use to lube the dvs with. Engine oil? Have no clue.

Normal peak around 17-18. Saw 20 the first day.

When I first got GIAC-x, I was getting spikes to 19-20psi and then it would plataeu and hold around 167-17psi until tapering off as I went above 5500 rpm. However, recently, I've been only spiking to 15-16psi and plateauing at 14 psi. I'll be checking TBB, DVs, and intake this weekend. Let me know what you find!
