Everyone is right bro, you dont need a tune nor do you need to change out your injectors at this point. I would spend the money on headers, sub frame connectors, rear end gear, or something else. You will see NO power increase by changing out your injectors, and as everyone said, a tune will not do you much good either. If you increase the timing a bit, i think you will see the results you are looking for.
Trust me..coming from someone with experience on the 94/95 computers, they are a pain in the ass and should keep the factory tune for as long as you can..
Lastly, AdderMK is one of the most, if not the most knowledgeable person on this forum as it relates to the 94/95. I would listen to whatever he says.
