stay away from the cobra computer, they are programed different than the standard 5.0 computer. i have a freind that has a 93 cobra who changed the heads and cam, he could not get the car tuned properly. he installed what i beleive is the 9al computer from a regular 5.0 and the motor now runs fine.

Another thing to keep in mind - the Cobra computer was used with a stock 19# calibrated MAF and the computer did the conversion for the 24# injectors used in the Cobra. If yoiu use a Cobra computer and an aftermarket MAF rated for 24# injectors, your gonna run too rich.

So the 70mm mass air meter for the cobra is calibrated for 19# injectors and not 24#

Yes...............but you use 24# injectors.
