Default Looking to upgrade the injectors

I'm looking to upgrade the injectors on my 95 Trans Am. Just wanted to see what size injectors people recomended and what brands people have had good luck with. Any advice is appreciated!

Why are you needing larger injectors?

My stock injectors are done so i figured i would upgrade them a little instead of putting back stock injectors. Or is this a bad idea?

How do you mean by "done"....

stock injectors are fine if you are still at a power level they can supply fuel for.

How do you know they aren't injecting the proper amount of fuel?

if they are rusty on the injectors you can do like a few have done and use a few different kinds of sand paper and polish them.. they do look good that way.

I'm just assuming. My car is extremly sluggish and down on power like its not getting enough fuel. Fuel pressure is fine and everything else i checked seems fine. This is just the next thing i could think of to check and found that they were rusty. Figured i would replace them and see if new injectors helped any.

If you replace them, replace them with another stock set.

Why do you think it will be ignored? I'm not the smartest when it comes to cars that's why i asked here. Judging by the responses stock injectors are what i should stay with so that's what ill do. No point in judging me when you don't even know me.

You'll learn that some of the guys on here are real jerks! I've learned to use google and other sources to answer my questions. The LT1 section of tech is my last resort.

Usually everyone is real good about helping me out since im not the brightest when it comes to cars here. I guess from time to time you will get that one guy that judges you for asking the wrong question!
