hi i have a problem i have a cobra 93' computer and 24 pounders with the stock 19's maff and my car runs like a crap the spark plugs are to white like lean do i need a maff calibrated for 24's? can i run a C&L calibrated for 24's or PRO M for 24's?
Pull codes and see what the computer thinks is wrong. My guess is that you've got a vac leak someplace that's leaning out your mixture. You may also want to check fuel pressure and ensure that it's correct. Is the meter you're using out of a Cobra or is it a GT/LX meter? From what I understand, there are differences in calibration between the two.

you can not use a meter calibrated for 30's from a gt. your best bet would be to find a pmas/pro m dealer and get one specific for the cobra computer. you could get a c&l and get the appropriate tube, but pmas/pro m would be my first choice.
I would personally ditch the Cobra computer and get a regular 5.0 comp., and get a PMAS MAF calibrated for you 24's. What is going to happen if you ever want to upgrade? You will surely need a chip at that point.
