Ive installed a new Zex nitrous kit in my car. Ive been running a 55 shot so far and i am getting great results. I want to go with a bigger jet size maybe a 75 or 100 shot. for a 75 shot i believe that i have to retard my motor 4 degrees, being that the car is my daily driver would this effect my cruising and city driving? Is there a device that can retard my timing on nitrous only or when i hit a switch? or would it have to be a manual operation?
