The TSB for the Power steering is 19-008-03
The window tint is 23-025-03
When they ran my truck in the system, it did not show the listed TSB's for my vehicle, but when they typed in the TSB number it came up. Make sure you tell them that you are experiencing the problem. You can do a search on the 3rd gen forum for those TSB's also and get more info.
AS for the EDGE EZ, I was running level 3 as I do not have gauges YET..... The idle just surges a little, more so when cold, but not bad. I ran the box and the boost elbow ... Everything else stock... except tires... .
