Recently my original volt blaster decided to stop working and I have been considering buying a new one or switching to a boost a pump.. Does anyone have any thoughts on if one product is better than the other? My original volt blaster worked well for many years but I'm thinking that a boost a pump will be much more controlled and consistent for my fuel pump will other things turn on when I'm driving my car. Below is a log of what happens to my voltage when my dual fans and second fuel pump turns on at the same time. Before and after the voltage drop the voltage is 14.2 volts and as shown in the log the voltage drops to 13.4.
