New gauges
So I installed new fuel,egt,and boost gauges. I also picked up the upgraded fuel spring kit from partsguyed. My fuel is reading 60-62 idleing before spring replacement. I wanted to see what the pressure was before the spring update. Apparently, I already have the blue spring? Should I take it apart or just leave it?

I don't think your FP reading is a definite indicator of having the blue spring, although it's possible. Where is your FP sender installed?
FP is dependent upon the condition of your existing FP spring, fuel pump, filters, and associated plumbing. Looks like you're in good shape as it is.

I'd say leave it. I run almost identical numbers with a custom fuel system, and haven't lost an injector since it was installed(3 years). Just my $.02.

I thought the blue spring was meant to bring it up to a specific psi range, not to augment to what you already have.....is this correct or am I way off?

That's about what I run with the blue spring. It's certainly possible that you already have it in there unless you know the history of the truck.

I bought this truck special order. I never put the spring in. I have had things fixed at the dealer and a egr cooler from strictly diesel, I don't recall any spring update.
