Help ASAP

My brother has been having problems even finding a smog test station in his area. It seems Cali is only testing 2000 and up autos and the smog test station is finding it easier to do those only.
 
I am trying to run 24lb injectors on my 95 5.0 and was wondering if I need to get tuned even if I install a 76mm maf sensor pre calibrated for 24lb injectors?

No you shouldn't have to have a tune. Mods are generally not ASAP issues by the way. ASAP is I need my car to run to get to work tomorrow, give me some clues on why it's not working.

if you are running 24lb injectors you need a maf calibrated for 24s.
You said it is running rich?
Look, a sentence here and snippet of info here ain't gonna get you good advice, just a bunch of educated guesses that will likely lead to wasted time and money.
#1 complete list of modifications
#2 a list of codes
#3 how did the car run before the mods
The last question is important because I've seen members come here with an ill running stang and they have thrown aftermarket parts at it because of random advice or internet suggestions.
