saw it has a boost gauge on it. Wondering everyone input on this. thanks

 

I dont know much about these monitors. It may not be as accurate but there is a app for ipod and android called "rev". that does similar things. there is a wireless adapter you have to buy additionally for around $150 I think plus the app price if your phone isnt hacked. Just a suggestion if you are looking for something cheaper. I personally dont have any experience with either of these. So take my suggestion as you wish.
