I love my Adrenaline so far and without getting the Pulse monitor you already get Boost, Fuel pressure, EGT and another that can be either oil temp or tranny temp depending on where you put the probe.(sounds dirty, huh?) LOL If you get the Pulse, I'm not sure what the changes are, but I know the screens bigger... Also, as far as Boost goes, I'd rather have an analog gauge, the numbers just flucuate too much for me on a digital. I can deal with digital on Fuel pressure and temp guages, they change slow enough they aren't hard to read.
