Default 347 tune question

I am wondering does my 30lb injectors and my mass air metter have to be tune together to make my car run problem. I am have small trouble with the car falling down when I get on it hard. I have order a SCT tuner and I am hoping it will solve this problem by putting everythign together and eliminating the govener. I was told that my car is just bumping up against the rev limiter but when I hit the rev limiter the car just bounce so the speak and it's not bouncing it's falling down when I really get on it around 4000 RPM'S. When I gradually ease into it agressively I can go higher without it falling on it's face and stops firing.. Also I need to know some good plugs for my edlebrock performer aluminum heads and where I should be gaping them incase it's the spark blowing out and also are those rings that come with the spark plugs necessary? and info on any of the issues would greatly be appreciate it.

yes you need the rings that come with the 3924 autolite plugs that you should be using with your eddy heads, they are sealing washers and allow plug to seat properly without gauling aluminum surface adn if it's not supercharged and it's N/A .045 to .050 gap will be fine
