Do I need A regulated return

My mods are in my sig, I did not build this truck I just purchased in as it sits. I have been told by a few people that I need to have a regulated return system. I want to make sure that I am getting enough fuel to the injectors, I plan on doing the blue spring mod and purchasing a fuel psi gauge. What do you guys recomend for my setup? Thanks

Buying everything to read fuel pressure on the cts sucks. Over 3 bills. Nice to read fuel pressure drop at wot. I had the blue spring for a year and recently checked pressure....72 psi. Just got done installing a custom reg return. Set it at 55 and it dropes to 50 at wot. This is the better way but set me back $540 for everything, including sending unit and edge expantion harness.

I'd do the blue spring and a fuel pressure gauge first. If you see fuel PSI dropping off then maybe a RR is required.

I see this more as a "want" than a "need" but you must get all the actual data first.
