Sounds normal to me. If you haven't changed when the PE table comes it it won't until WOT due to saving MPG. Often factory delays it till 5000 rpm and 55 kpa. I prefer to enable it at 85 kpa and 2000 rpm. But be prepared to doing some serious fueling adjustments in PE

 

I wasn't going to say anything at first, but.....to the original poster, that "TurboGibbs" guy doesn't know wtf he is talking about. He's just a crazy old drunk. He doesn't even own a truck!

 

Hey! I'm not OLD!
