One thing I've noticed on my ecoboost is those turbos eat gas like crazy. Stay out of the boost and the fuel economy is amazing. Get into the boost and you're in single digits. Why not have a disable boost option that you can select via dash switch, giving you the option around town of normal aspiration power only. Sure the power would suck, but for city driving it would be adequate, no worse than any V6, right? And the mileage would be amazing. Need full power, flip the switch. Doesn't seem like it would be too complicated.

It's actually a pretty difficult thing to accomplish. The tune is calibrated for forced induction to be heavy on the fuel to prevent detonation under load and a automatic variable setting waste gate would be needed in conjunction with a independent tune

Shoulda got a 5.0

A turbo is a detrimental part of the induction system. While Disabling the turbo completely is likely impossible, preset computer settings in the multifunction display to set lower boost levels seems more realistic. Maybe "Economy" "Auto" and "Dynamic" settings to control boost levels. All it would do is change the boost levels through an electronic boost controller. That is 100% doable and there are aftermarket EBC kits.

GTFO with that! None of that in this thread.

For that to work like you mention you'd have to have a variable exhaust manifold that has some sort of valve that either goes to the turbo to produce boost or bypasses it to run like a NA engine. The turbos would have to be mounted farther down for the valve to work and things would just get too complex and most likely super costly

Don't forget the intake side of this. It wouldn't be to difficult. Have a valve that routes the boost to atmosphere and draws air from a separate intake/air filter. Problem solved.

what if you just tune the BOV's to be 100% open... wouldn't that cause a "pass-through" effect on the turbo's?

Ford already did it. It's called a 3.7 V6.

That being said, the closest thing to the OP's idea is 5Star's econo tune.

That's the cool thing about having a supercharger Vs Turbo. You can control when and how much of the pressurized air enters the intake. The Wipple system does that.

I give the OP a lot of credit...few mention how much fuel these engines will consume when getting into the go pedal or pulling. It takes fuel to make power...no matter what you drive.

I pull a 7 X 14 enclosed trailer. Anytime I push on the gas it is making boost and using lots of gas.

8 to 10 MPG!
