My manifold temps will go up out of nowhere while I’m cruising with the engine in vacuum (-12 to -1 boost), and this is normal with the EGR system functioning. If I give it a little boost, the charged air cooled by the intercooler will bring the temp down immediately. If I could delete the EGR I would, but you can’t do that anymore on Cobb because of the CEL.
Do you have a protune/etune? Or are you using an OTS tune? When I first installed my intercooler I would see my intake temps rise when I was under vacuum at -5 to -2. Going into boost they would drop immediately, I was running the Stage 2+ tune from the accessport. After getting protuned this no longer happens.
@@alexs_wrexyeah I just flashed the first base map to my protune and car feels great. I came back to this video to look at best gauges to monitor so I will definitely use this as a guide 👍
My afr correction 1 is close to 0 in idle but my af learning 1 has gone all the way up to 29% and i’m on a etune. Driving it’s not anything concerning, like -2.75-6.25.%
Does it stay at 29% for a while or does it only stay there for a few seconds? Double check your intake and charge pipe to make sure there's no leaks. Whenever you get the 29% reading do a Log and send to your tuner. They should be able to let you know what's going on. But if the car drives fine and all your other readings look normal I wouldn't worry too much.
8:23 Thought you were filling her with diesel! 🤣
Lmao nah. A diesel conversion would be wild on these cars though.
Good video brother
Thanks man. Glad you liked the video.

Thanks for the info. I’m debating an AP soon and just wanted to make sure I’m ready to start performance mods
One of the best investments for these cars for sure.
