10%+ Better! How to and HOW NOT TO LOL! I gained horsepower and got over 10% better fuel economy with a simple increase in fuel pressure. After installing upgraded Bosch type injectors on my Range Rover 4.6 GEMS engine I was told they need at least 41 psi fuel pressure. Standard regulator gives 36 psi so a gentle ‘squeeze’ was needed. I show you how I did it.
This is getting ready for a Tornado Systems ECU upgraded chip gets fitted (next video).
This is how I did it and if you choose to use information from this video and try this yourself, then you do so at your own risk. Working with fuel systems can be dangerous!
