anyone on here using the dash daq I'm thinking of getting one and was wondering if i want to see afr and boost on it do i need a 2 bar map? and why? Sorry still kind of a newb

 

A 1 bar map only goes to atmospheric pressure, no positive pressure (boost) readings. The 2 bar will allow your gauge or you to see past the 105kpa. If you change your MAP that your pcm uses, then you will need a new tune as well.

 

Thanks is the 2 bar gm one the best one to use?

 

Thats what i have used for the last 2-3yrs with no issues

 

do u know the part # or what it came off of? Thanks
