Review: Eat your heart out Aeromotive! - Needed an adjustable regulator for a new fuel injection system (Aces Killshot, which from what I can tell they still have some bugs to work out of their software👎) and although Aeromotive makes quality fueling components I just couldn't justify their price for a component that might not even fix my issue. 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.
Review: Good Buy - Nice quality, haven’t ran it for long but so far so good

*by W***N on September 27, 2023*

Overall product is good. 0 leaks. Currently on my 2002 is300 return line setup. Only thing I’m not a fan of is the whole unit is metal BESIDE the 1/4 barb for your vacuum feed. It’s plastic so if you accidentally hit it I’m very confident it will break.
