Rick,
The seller is LYING or IGNORANT.
The 93 Cobra meter is not going to work with the A9L.
Ford does not calibrate MAF meters to the injector size.
Ford calibrates its MAF meters to the ecu.
Ford uses a different setting within the ecu for injector size.

ONLY the aftermarket meters are calibrated for an ecu AND injector size.


The 76mm is probably a C&L, correct?
You can recalibrate the C&L meters by swapping out the sample tubes. Sample Tubes usually cost 25-30 bones.
Also, make sure you are using the stock (for your computer) MAS (the black box sensor) with the C&L.


C&L's aren't the best meters out there, but if you already have it, why not give it a shot...
Especially if you still have the stock air box in place...
