I agree with the others, the IAT gauge would be good. The boost is nice, but I think IAT would be more usefull to monitor to help you keep all your power. I have a triple pillar pod and have AFR, boost and oil pressure. I couldnt find an IAT gauge when I did my install. I have since installed a Zeitronix Zt2 so I can data log while running. Just my 2 cents worth.
