Just curious where the different air intake temperatures are taken and what they should be. I have two X Gauges, IA2 and IA3, but I would assume there is a IA1 as well. IA3 is always the highest so I assume this may be post-turbo, pre-intercooler? IA2 is a little lower but seems to get kind of high around town (120 on a hot day). What's normal for these readings? Anyone else track them? I'm a little OCD but after 8 months of frequent regens still no answers so I keep a log of any data that seems relevant and might be helpful to the dealer if issues arise in the future.
