I've been messing around with my Jr just doing some testing, as we all seem to do when we got one of these. I first tried sw3, tq1, tm3 and POD set at 85. My truck ran awesome and seemed to be getting great mileage as well. It literally didn't smoke at all (running lean perhaps?) I then switched to sw3, tq1, tm4 and POD on 85 still. My truck seems to pull harder and spool faster on the highway but it will smoke out the car behind me. From what I understand, the lower the smoke, the better the tune is? I'm more or less concerned with the EGT factors. I have searched for these similar settings and other opinions in other posts but I'm not quite seeing what I wanna know. Any input would be great.
