As far as I have been able to ascertain, fitting a 4 bar FPR will help safeguard the engine at the top end with a different N75, but it'll ****** up the midrange and bottom end...I may be wrong, but as far as I know, you need to have a map with reduced injector open times to reduce fuel where you don't need it. otherwise it'll run rich and possible wreck the car etc.
I believe it would probably be OK at idel though as the ECU will be in closed loop mode and should compensate.
To be honest I'be wondered the same about the 4 bar FPR...

I might just get one and experiment a bit...
I was going to do some logs...
Standard air/fuel ratio
N75J air/fuel ratio
N75J/FPR air fuel ratio
Plus standrad and J airflow readings.
Should get enought data from that to see if its alright or not
Anyone know how much the 4bar FPR is?
Cheers
