Okay, I'm by no means a Super mechanic or a pro tuner but I was curious as I'm getting into it what is the best choice when it comes to reading Boost, A/F, Oil/Water temp. I only ask because I noticed that my 2010 MR dosn't show me the Oil/water temp and also I was going to get a boost gauge but came across this.

Now to me that looks super badass but I was curious if there's a problem with digital display vs actual gauges.

 

The only issue with the MDF2 is that

1. Its expensive
2. There are a lot of extra things you have to buy to fully utilize it
3. It takes up the OBD2 port
4. it has the same limitations of anything attached to the OBD2 port

Other than that its pretty nice (I've seen it at a few meets).

 

SO what are these limitations? Because if i install the sensors I would be gettin real time readings right? I heard the OBD2 slot was delayed in it's readings? Just curious before I spend a ton of money on something, you know?
