onya Polar, another class contribution

Yes 43 psi is the typical target with our regulators. Mine is set at 40 psi or 276kpa. Should I upgrade the turbo in the future and want to lower IDC's retaining the 440cc injectors, increasing fuel pressure another 10 -15% would be the smarter option. You can not do that with the OEM item.

Having a wide band lambda on your Motec is still not going to tell you every cylinders individual temp, its still just an average. You will never know if there is an imbalance using your existing method.

Research measuring each cyclinders EGT is the only method and it would be great to hear from any one who has done this. I thought MRT had but I am unable to find it atm. They even recommend a twin fuel regulator set up?

I hear what you are saying about that tiny shitty little excuse of a regulator having a simple job, but when is a better item a problem?
