Ok, so I know you guys aren't losing sleep over this but I'm bored and figure this would help anyone that's a PCM noob like me.
So, around the 2nd day of driving the knock pretty much went away. It also took about 2 days of driving to start to notice any real difference as far as firmer shifts and improved performance. It actually caught me off guard as I went to pass someone it skipped down and I blew by them. So I fill up with premium today and I did a little MPG test. For work today I drove 125 miles 75% highway and got 29.6MPG!
I had only been getting around 25-26 and only hit 29 twice when I was on the turnpike and it was ALL highway. I'm really impressed. I guess it just needed driven a little for the PCM to figure things out.
