This truck feels light as a feather now with all the added healthy power from this little groove! The customer (my boss) REALLY likes the driving feel of barely having to touch the pedal. He said the tailpipe smells like a hairdryer, and is the first time EVER experiencing that. Way to go RON!
Torque & mileage gains will be very nice for pulling the fifth wheel camper on their next trip!

Did the customer ever report any improvements in power or mpg?

Yes him and his wife both love driving it. They say that barely touching the gas pedal is all they need to do to get the big beast moving down the road! His tailpipe is like her hair dryer, but they found over 10 problems relating to fuel delivery etc. To name a few..
*gas tank line leak!
*bad map sensor fuse
*faulty 02 sensor readings (likely from map sensor fuse?)
* loose spark plug showing carbon blowout around it
*exhaust manifold leak
*exhaust leak before post 02 sensor
*bad fuel pressure regulator
* pcv valve still hooked up! (He listened to mechanics)
Once those are fixed, he should see a very nice increase!

If I haven't been straight enough about it before, or people haven't reached the same conclusions as me, it's time to be straightforward and forthright about the relationship between MAF, MAP and o2 sensors as far as fuel delivery:
If any of them aren't working correctly, or the numbers the ECU reads from them don't jive with what the factory has programmed it to be happy with, fuel delivery will default to maximum to protect the engine.
This is why I'm an advocate of keeping a clean MAF, using a MAP enhancer circuit, and putting an EFIE on upstream o2 sensors. The groove makes a waveform in the intake manifold that the computer may not understand based on what the MAP is telling it - we can correct/modify the signal to the ECU. further, because we cause a lean burn condition, the o2 sees more oxygen in exhaust and tries to correct for that by delivering more fuel - again, we can correct what the sensor sees.
if any vehicle doesn't respond to the groove, assuming there are no vacuum leaks or other maintenance deficiencies/defects that need correcting, the computer must be fooled by electronic hacks. MUST.

I Agree Greg. The computers in our autos are just there to keep us burning more fuel than we really need to. You've pointed out the obvious solutions. Your comment also made me think of Shell Gasoline. They had a gimmick of adding "clean burning" Hydrogen to their fuels. Unknown to the duped consumer is that even if the fuel would burn cleaner, the cars computer will sense that its too clean and just dump more fuel until the O2 sensors tell it to stop. Have to fight tech with tech.
