dial up c&l and order a 24lb MAF sampling tube and change it dude, don't mess with the a/f ratio, that is only really a way to trick the digital output of the MAF to the computer so it thinks its running a cal'd 24lb'r, but it's the most typical way of doing it, why the increase in injector size?

Your car will run like sh*t. Its not MANDATORY but you will need a tuner to correct everything if you want to swap out the injectors and not change the MAF.

good idea, if you have the cash upgrade the MAF to a 76mm from c&l tuned to 24 lbs....

It is possible that the previous owner knew what he was doing and installed a 93 Cobra computer and MAF along with the 24lb injectors.

Check the part number on the MAS. The Cobra will be 'F1SF' and the A9* series MAS will be 'F1ZF'

Have you pulled the codes?


C&L is not the best quality MAF meter. They work great for many folks, but in some vehicles C&L will never run right.
PMAS may be a better option...
With that said, I ran a C&L for 10yrs with no noticeable problems...
