With my new addition of DD2's and the warm 80F weather we are having around here, I had to change my jumper from the most aggressive to the middle setting. No mater how hard I tried, I just couldn’t keep the freight train from smoking.
Now it has the same power in mid to WOT as before, it is just a little more manageable at the bottom end. I have to apply just a tad bit more go pedal then before, but the smoke is almost gone.
I also noticed my cruise control works much better with the EZ on the middle setting. It was very jerky before. The truck would want to lunge forward/build lots of boost then left off. It would do this over and over again. Now that I changed it to the middle setting, the cruise acts more like it did when it was stock.
All the settings will fuel the same amount, just the least agresive ones wait for more boost before they dump the fuel...
