I was looking at getting the Sard FPR and noticed that some of the ads talk about it only being able to support 450 hp. I was wondering if anyone is using it at higher horsepower ratings. I'm talking about the standard regulator. If it doesn't I may just go to the Aeromotive unit. The racing regulator is like twice as much. Though I do like being able to use the adapter for the stock fuel rail. Any thoughts?

 

Go with the aeromotive unit with dual -6an ports.

 

I've had both small (up to 450ps) and currently the large Race (over 450ps - 1000 maybe). They don't list the flow rates, only pressure. The race bolts on to the UIM perfectly if you are single turbo. I was going to buy the T-Reg pro becuase they claim the smoothest and most acurate flow but now I want to try Synchronic becuase they also claim they are the fastest and theirs bolts on to the stock fuel rail.
