Im a little confused by this.... my tuner asked me to get a Boost sensitive Pressure regulator before I come to get tuned. Now which FPR's are boost sensing? I thought aftermarket FPR's were adjustable. I guess i dont know much about fuel systems with boosted cars.

 

Your tuner is talking about a FMU, which IMO is not the best way to provide extra fuel.

But I dont see why he is suggesting you get one before you come down to get it tuned. Maybe he did mean an adjustable FPR and yo heard him wrong? What is your fuel and EMS setup?

Nope he told me a boost sensitive FPR. My jackson came with an FMU but im going to be using Uber, I have RC 440's im gonna get a new pump and im looking for an FPR and underhood gauge also. I didnt think I could run the Jackson FMU with Uber

 

Time to get a new tuner.

Ok, if you are running larger injectors and Uberdata then you dont need a FMU. IMO a stock FPR should work fine too, unless you want that extra degree of adjustability. Does your tuner know that you have larger injectors and Uberdata?

hehehe, that's where I was getting to. If his "tuner" knew he had bigger injectors and Uberdata, then it sounds like his tuner is just talking out of his ***.

 

Whoa my mistake he said a non boost sensing FPR.....
This is what the tuner said and they are a HT sponsor:

I would suggest that you get a fuel pressure regulator that isn't boost sensitive. Even a simple B&M would be fine. FMUs and boost sensing FPRs while running a tuned ECU or EMS will cause conflicts. The FMU will throw in more gas by itself, and will
disregard the programming done on the EMS. I'm giving you a heads up before you make a decision.

Now im going to be running uber so I thought I needed an FPR and it would be safer than the Jackson FMU.

 

Just get a nice FPR, it is just used to set your pressure, just incase you get close to maxing those injectors.

 

Hey ill be sending you the p28 in about a week or 2.... im also gonna want a stock oem chip burnt for it to.

And for the record 93turbo16 is not the tuner that I was speaking of.

 

sounds good man. good luck with the setup in advance.
