Unplug the gauge, at the motor.... Then report.

specifically trucks with a manual trans, as we are most likely more sensitive to things like surge

my surge came back. specifiably when I went back to the TNT/R.

I can now listen to the stereo and full volume, and the truck does not buck anymore with the cruise set. Seems to accelerate faster as well, smoother.

I need to test a few more smarty settings to confirm. Give me a day or two. I know for a fact that I have a lot of surge under extream light peddle input on TNT/R #7 Timing 3, rail 4, tqm 1, highrpm. I unplugged the gauge and went to TNT/R #9, timing 4 and I have less smoke and better acceleration. I don't think this all has to do with timing on 4 vs 3, I'm going to bump that up to 3 on my way home today and observe.
