Low Fuel Rail Pressure, HELP!

[heady2010]

I currently have a present fault code on my car in relation to fuel level low, do the pressure sensors often fault?

[Keith@APR]

This is common at stg2 as the extra airflow requires more fuel and the pump can't meet the requested amount. I find that A session on the Dyno and carefull changes to the map should sort you right out.

Only stg2 stuff I don't get this issue with is when a twintake is fitted   whenever I am mapping stg2 with evoms or ITG, BSH intakes I eventually hit this issue and have to back off the requested boost and requested load and add a little ignition advance to compensate.

If you need any help I am always at the workshop on 01915239540

What's the difference in MAF g/s with the intakes that cause the problem and the one that doesn't?  Just curious.
