I heard this and wasn't sure if it was true.

 

If you have a Standalone or a custom map ecu the fuel economy would be better than a stock 300 even on highly modified 300's as you can have a low boost setting.

 

I realise when you put your foot down though it completely goes out the window and would use loads loads more but if it was to be driven at a steady pace would it be better on fuel?

 

I think there could be some truth in this for several reasons.

 

1. lower boost setting than stock.

2. custom map made percific for your excat car not just generic off the shelf.

3. More effiecient.

 

 

Just a thought as with the fuel crisis getting your chip mapped for your car may be a penny saver and also give you more power.

If the car is tuned properly and the mixtures spot on then yes it will be more efficient at crusing speeds, but every time you dab the giggle peddle it will go out the window and guzzle it. I know when I first had a boost controler I also had a AFC to remap my injector duty and air fuel/ airflow and My car was about % more fuel efficient than it had been.

ooo.... so there is some truth in it.

 

Interesting that.

 

Everyone buy new chips :D
