Hey Trent, I have a Blitz I-Color installed for about 6 months now. Very easy to setup and simple install. It has an auto-learning mode, so you just set the boost, go for a drive and it learns not to spike. Many other features though. There is enough wiring in the kit to install the solonoid right up the front of the car in the cool(ish) breeze and it actually suits the zed as a couple of vac/boost lines need to be t-pieced before joining to the soloniod. The instructions I found were easy to follow and I have never had a problem since. Only thing I had to make was the alloy bracket for the soloniod.
If you need any help with the install I can take a few pics for you. Only too happy to lend a hand.
