So I went with Ktuned fpr. I already had the lines run when it arrived so I made my 2 hose connections put sealant on the Guage threads and tightened it into its port and started cranking the motor. Eventually I got my 6.3l 385 stroker doing something resembling an idle and looked at the gauge. The needle was pinned right to 60psi and didn't waver from that until I turned the adjustment screw down to 48. The regulator and gauge worked flawlessly and look to be made from quality materials very similar to Aeromotive. The problem with these gauges is when they get hot under the hood they usually start to dance, reading pressure inaccurately. This one does not and is worth every penny I spent and will likely again.
