Boost Controller

One of my cars is a Mondeo TDCi which has been remapped by MSD. Now is there any way I can get a boost controller to lower the boost for better MPG?

If so, what are the pro's and con's?

Cheers

I can drive economically if thats what you mean, but if I can turn the power down when I'm not using it surely thats a good thing.

Less boost = less bhp = better mileage

no,if you dont put your foot down as much there wont be as many exhaust gasses which means the turbo wont boost as high which means less power and less fuel.if you only using part throttle etc the turbo wont put out full boost like if you hammer it.

yes mate,unless you are going to be putting it in low boost mode and then booting it there! and besides you probably need to adjust the base boost pressure on the wastegate as a boost controller cannot adjust below the actuator boost pressure.can only increase it. driving at part throttle and just milling about saves a LOT of cash,especially when you dont need to shell out the silly money commanded by boost controllers!
