I am getting ready to do some mods for my challanger 5.7 R/T and need some advice. I want to put on a 90mm throttle body, cool air intake, high flow fuel rails, 50lb fuel injecters, JSA long tube headers, high flow cats, and go to a custum 3" exhoust. I called a guy to give me a base line dyno and told him what i was going to do and asked him if he would tune it for me when i was done. He told me i would burn out the plugs with all that and 50lb fuel injecters is to much. Can someone give me some advice on how to make all this work.
