Well, a week after installing a BPD oil cooler and an MTW stage 1 turbo, (both of which I am really happy with thus far), I came out to go to work and get a crank no-start. I did see ~350 PSI icp pressure on my CTS, I was in a hurry to get to work and didn't look very hard. I'm thinking IPR issue, I need to go home tonight and hook up AE. Any thoughts? It also got me to thinking, which is dangerous, does anyone have a permenant system setup to data log? I am thinking kinda like a security camera so that if you have an issue, you could go back over the say last 10 minutes of run time and look for issue? My truck was running fine the night before when I got home from work and I don't recall any bad readings on my CTS, I usually look at the screen when I turn the truck off.
