Mods and fuel

Alright... I have been searching and searching all over the place to try to get an answer to my question(s). My background... I've had several 5.0s (87,89, 86) over the years and never had any problems with mods. now I have this beautiful 95 red convertible with less than 60K mikes on it and keep reading about 94-95 computers being a pain in the butt.
I have in my garage just about ready to go, the following parts...

Ported upper and lower 95 cobra intake
gt40 heads off of a 95 cobra that are getting work done now (light milling and polishing and smoothing out the rough spots)
24 lbs injectors
Steeda #19 cam

THe car already has
K&N
pulleys
exhaust
gears 3.73

so the questions are...

Do I need the 24lb injectors?

if so what is the best option to keep the computer happy if I do. Dyno is not an option as there is not one close enough.

Can I get away with getting a MAF that is calibrated to 24lb injectors. I have also considered the SCT Mustang 4-Bank Eliminator Chip at American muscle.

I know you guys have probably heard these before but I swear I have searched and keep coming up with different answers. Any help would be greatly appreciated.

okay for starters if you put in the 24s you'll need a maf calibrated for it so add that to the list. i would do them, your going to be pushing those 19#s pretty hard.

the SCT chip won't help you as they can't tune for stuff like cams and heads so that option is out. where are you located that there isn't any dynos around?

Bolt on the intake. Don't bother with the injectors or cam unless you're getting cylinder heads. A tune is not necessary until you change the cam/heads, or if you add a blower/turbo.

Oh yeah, and get gears. You'll notice a much bigger difference from that than you would from the mods you mentioned anyway.

Oops I forgot to put the word "heads" after gt40. I have the heads almost ready to put on the car. I do have 3.73 gears.

I am in Tucson, AZ I believe the closest place is Phoenix but it about 2hrs away. Tweecer or something like that is the only other option?

Your car may or may not run good. My car idled like crap with a trickflow stage one cam. Some people have put in bigger cams than me and been fine. So I dunno what the trick is.

x182dan,

what mods did you add when you did the cam?

i have almost the same mods except i have svo heads and typhoon intake and with the steeda 19 and 1.7 roller rockers i had to idle the car up to about 1200 so it would idle correctly other then that it ran fine... i did notice a huge difference after a tune though....
