Info to do with what you want.........
I put an adjustable fuel pressure regulator on my car. Heres the top tip...
I always keep an eye on the MPG....With the standard 3 bar FPR my car was averaging 24.8mpg. Put the adjustable FPR on the car and wound up the fuel pressure to 3.4 bar.
No lambda warnings (ie...its running too rich etc).
Kept a keen eye on the MPG and its gone way UP!! Now got to an average of 28.1mpg and still rising (no change in driving style).
The blue injectors come from the ME7 T5's, they use 3.8 bar pressure. I guess that at the 3 bar the injectors arent spraying as they should and by lifting the pressure they are spraying more efficiently and hence now burning the fuel much better. Cruise at 70mph and now gets 45+ mpg easy.
Just thought I'd share my findings.
No responsibility taken for those who do this and kill their car. your choice to do with that info what you want to.
(perhaps just my old FPR couldnt handle the high output from the uprated fuel pump. you never know).
