Two 92's one runs like , well u know

[Ecoman]

No codes except ocasinaly from diff torque issue ?

One runs great.
Other one seem to run ok yet mileage down and bogs ?

and Trany does a little double shift sometimes

Main issue other than poor mileage is bogs and lack of power when accelerating in harder than normal driving
Yet sometimes it catches
High rpm seem ok.
Just 2500 to 4000 weak

Normal driving is fine other than mileage
In town half
Oh highway crushing at 60 mph down 20%
Highway normal driving down 35%

Ideas

We have swapped MAF , tcu, ecu etc from identical other car . No change

In auto Trany shifts ok without slipping
In manual mode it shifts better with much less bogging issues yet still lower in power

Mods are ecutune stage 1 and tcu with valve body's reworked

Any ideas would be appreciated.
