Stick with the stock injectors for now. You aren't even making them break a sweat at that point

at what point would the stock ones need to be changed? The stock ones are 22# correct?

there are 30# injectors on my car now. the SC manufacturer recommended 36#, and stated that they use the same SC and 42# injectors on a truck. This gives them more flexibility with tuning.

crap, guess I didn't notice ya had the supercharger... 1 question, do you just have the stock catback with weld in mufflers? if so I would prolly say you should look at a good catback and open up the exhaust. No need to go from a 2 1/2 xpipe to 2 1/4 catback .. As far as the injectors I would think you would need to step em up a bit, but I'd wait for someone with a supercharger to chime in... Also why just 6 pounds of boost? You should be able to run 8 with no problem on a stock block with a good tune.

my friend has a 1999 mustang GT and his stock came with 19lb. injectors. Mine is 2003 and it came with 24lb. injectors. I dont know when they changed them.

I do not have the stock catback system. I have a bbk X pipe without cats, and spintech mufflers.
