Downshifting
Will your car get worse gas mileage if you engine brake alot?
If you tend to downshift to slow the car down most of the time, and use the brakes less and less, will the injectors squirt gas just because the rpms are higher, or not because the throttle/tps is closed?
I think one of those Interceptor guages could answer this, but i dont have one.

You should get better MPG techincally since we have DFCO (Deaccleration Fuel Cut Off). Anyone with a wideband can see this. You can also hear the exhaust tone change.
It basically cuts off the fuel so you can just coast.
