Rang up a dyno shop today and they reckon they can fit and tune an adjustable fuel regulator on a N/A 4l falcon and is good for another 5 rwkw. Anyone tried this all are they just talking s**t. $300 was the quote for dyno tuning and fuel regulator.

cheers ..

There is an element of truth to it. By reducing fuel pressure in the rail, you are able to lean out the fuel mixture.

Unfortunatley, EEC-V has constant learning capabilities and (within a %) is able to adjust the injector pulse widths to compensate and bring the fuel ratios back to factory spec.

4.9 EF Futura has pretty much covered it. Not really worth $300 IMO....

They might aswell take your 300 and do a few dodgy dyno runs... if there generous they might give you 15kws haha
