don't run a dry shot in my opinion then you are relying on your injectors just go with a zex kit #82021 best kit for the car imo. and that is what i got, i am installing it tomorrow, just want to know if i need to do anything with timing to run a 75 shot or if the stock computer will pull timing automatically under spray, i know 55 shot requires 0 timing adjust. so i am fine with that i would just rather spray the 75. im sure 65 would be fine also without doing anything, with that wet kit it has fuel controller and nitrous controller that optimizes bottle pressure and never runs too lean or too ruch it will adjust itself basically to be the best it can. it is a great kit i used it before on my srt-4. you would be very happy with it. but someone let me know about the timing thing here if anyone has good knowledge about it, thanks
