Be careful....
Tom , is right... Brett ( from EDGE),has told me, and so have others in the know, It is not recommended to change settings, under load ( any boost pressure) as it is very hard on the injection pumps. It could cause premature failure. In other words if you are going to drag race someone, set it at the desired setting before launching. Or if you are cruising along, no matter what speed, as long as you are down on the boost, simply let off the throttle, Zero boost, push the comp button to where you want to be, nail the throttle. Since I only use EDGE Products, I would recommend caution when using other fueling boxes in a similar manner.
