SC @ 80-85mph averaged 20.10 mpg the last 2 days on my return from Michigan to Fort Worth. The cars computer continually projected 38 to 42.
My conclusion, When RMS did the reported "reprogramming" of the DME, they either did nothing, or they dorked up big time.
I am continually receiving fault codes pertaining to O2 sensor limits being exceeded. (I installed 4 new O2 sensors while in Detroit.)
Will be contacting RMS tomorrow (Friday)

. Overall performance of their product is disappointing. The vehicle, when pedal is fully depressed acts as if the throttle blade (butterfly) is being rotated fully closed, thus the vehicle lacks any power. In fact the engine wants to stall.
Will be inquiring as to remody. Am thinking of drilling and taping for a screw to put into the throttle body to stop the butterfly from fully closing. (If that is what is happening.)
What i thought was going to be a major improvement is so far............ a major disappointment.
If no fixes are recommended by RMS then i will have to resort to ingenuity to teach myself how to drive this "potential" beast.
