Top is AEM tru boost which is both a boost controller ( 3 stage of boost) and also a boost gauge.
I will be putting the aeroforce gauge in that location soon so I can have a warning if there is a methanol system failure.
I set it up so at 2 deg of KR it lights up red. Down low it's hard to see.
At the moment I never ever seen any KR but if my methanol system runs dry or fails to inject my margin of error is more slim at 18 psi of boost + on pump gas. it's nice to have the warning in your face.
