k, so i got a 88 supra 7m-gte, has a cx t61 turbo on it, fuel pressure reads off the charts, thought the gauge was broken but i bought a new 1 and started it and it went all the way maxx, so, its a adjustable fuel pressure regulator, i turn it all the way down and it will Not go down on the gauge. Any ideas?
