Engine working too hard?

[Jon_MothaFkn_Adams]

I tried searching to see if this a known issue. I have 20k miles on my 2.7 Badlands w/ Sas. I've already had a new engine put in it.
Now, when I get up to about 75 on the highway, it feels like it's working way too hard. The RPMs aren't super high, only around 2200. But, it feels like like it's slogging through mud. It definitely wasn't doing this a few weeks ago.
It also won't get out of 4A when you change back to normal mode from slippery mode.

Anybody heard of this?

What kind of boost levels are you seeing? I wonder if you blew off some piping.

I haven't looked at that. I'll check later.
