Has anyone fitted the above to their vehicle? They are advertised at £125.00. I don't cover much mileage in my Freelander, and average around 6500 miles a year. So it would take a long time to recoup the outlay. But, with better pulling power and increased acceleration, I'm tempted to buy one.

All tuning boxes do is fool the engine into spraying in more fuel. I'd be highly surprised if you saw any actual economy improvement (actual economy, not dash readout)

Thanks
