Bigger air mass flowmeter (MAF)

Bigger air mass flowmeter (MAF)
So THE JAGUAR AJ6 ENGINE - 3.2, 3.6, AND 4.0 LITRE / AJ6 Engineering says the air mass flowmeter needs to be bigger to get more air into the engine. They also say that after boring out the unit, its circuitry has to be recalibrated.
Have you tried this modification on your Jag? Do you know where I could get the flowmeter recalibrated? Or do you know of a bigger flowmeter from another car (Mustang???) that might communicate with the ECU and not need recalibration?
Apparently doing this mod in addition to a Growler-type air filter can yield 20 bhp and is a good first step to waking up an engine.

Thanks for the suggestion, Warren. I'll do some research.

Yes, the MAP (Manifold Absolute Pressure) sensor is placed after the throttle body, the LSX guys retune the GM ECU.

MAF Location
So the V-12 has no air flow sensor? Dammit... I was hoping that was my issue. Guess I need to start taking more things apart now....

After having the transmission rebuilt (4L80-E), the transmission shop hooked it up to their computer to test it out, it ran through all the gears successfully including reverse. Plug it into the car, and it remains in LIMP mode like it did before the trans got rebuilt.
Took it to a European only garage, they had it for a month and a half to try finding why the trans won't shift. One guy there who's a specialist on Audi's told me that he had the same thing with an A6 once, and all it was, was the MAF.....
