I do. Its far more accurate. Out of curiosity with a stock fuel system I put a gauge in the bowl and one in the back of the heads. Wot the bowl would hold about 45psi with the blue spring. However the back of the heads would drop to 35ish.
I can only imagine what mine gets too back there, thinking the last injector is seeing what looks like a leaky faucet...
I can drain my bowl down to 25-28psi before it shifts into OD, that is before and after the blue spring. The blue spring kept my pressure higher for longer though, but before I could drop it to that range before I was at 50mph
