Me too W_S!
ill believe it when i see a dyno sheet
This is about the silliest thread I have EVER read all the way thru. What these youngsters don't have a clue about is velocity. From the factory velocity is a prime tuning element. My 4.0 has VARIABLE intake runners. Which keeps the velocity UP which in turn FILLS the chamber better at lower rpm.
Changing the size of the intake BEFORE the Tb does nothing until an rpm is reached that would be taxing the original intake system.
The tune required for a larger maf is simply to tell the engine that the new maf is actually passing MORE air than it is saying is passing. Then when tuned the new maf will act the same as the older smaller one did.
I highly doubt ANYTHING done in front of the tb could cause a happy noticeable improvement.
Now the shop putting a "tune" in the computer could change some parameters that could show some power improvements...at the cost of mileage.
Remember more power takes more fuel.
As we all know for sure...The engineers at Ford don't have a clue, do they. Yep with all them millions of dollars of equipment and computers, and education.... it is easy for us in our driveways to figgure out how to get more performance and power out of our rides then them guys could.
