Anyone ever made their own pigtail?

Or would it be easier to just put in a relief valve?

tryin to get away from defuelin and limp mode, with out spendin alot

you are better off making a pressure regulator instead of a blow off valve. loot at itp diesel's boost regulator. i don;t think you could build one cheaper.

You could install a Vacuum "T"* in the Waste Gate (red) line . Doing so, some of the Boost Pressure is bled off. The WG won't open as fast. More Boost, longer.
