I have had my Mini Maxx and full deletes since I bought the truck last summer. Never had a problem. Now when I come to a stop I usually wait till the egt's are down around 400 before turning it off. It usually only takes 30 seconds to a few minutes depending on how hard I run it. Now it just hangs at like 590. It will take 10 mins for it to get below 500? I have the exhaust brake off and haven't changed any settings. Does anyone have any idea what would cause this? Oh and the egt's look normal when driving and under full boost etc. Just hang high at stoplights or when I am stopped in park before turning off. This made me believe it may not be a bad sensor? Thanks for any help in advance.......Craig

Are you sure that your probe tip is not in too deep and touching the inner wall...the manifold is probably still 500 degrees for a while after driving

That could be it. I will check and see if the probe came loose. Thanks......Craig

Also let us know what tune you are running. Are you on the hot tune with timing on level 2???

Clean your air filter

I have the AFE air filter and it is clean as a whistle. Truck only has 5600 miles on it so I only run the mild and wild tunes. Do not have the fuel timing adjusted that is all stock. Main reason for the tuner was to delete and give a little extra power. Stock mufflers, egr, cat and dpf delete, AFE intake. I didn't get back to my truck yet to check the probe. This was all professionally installed.

Looks like the probe is bad. I updated my software and firmware etc. now it just reads 0. Going to get it warrantied.
