The TST PM3 is the TST PowerMax 3. This is a 120 HP box (its direct competitors are the Edge Comp and Blue Chip FMS) and is available with a remote that allows 9 levels of adjustability between 40 HP and 120 HP. While the TST box does some timing, its a very aggressive fueling box, especially on the low end. Great box for the higher power crowd.<br><br>As for stacking, we've noticed that in the past couple months, either Edge or TST has changed their programming, and stacking is no longer an option. We've tried with both a TST PowerMax 3, and a TST PowerMax 3 Competition, stacked with an EZ and a Bully Dog Torque Dog+. The stack will actually rob some power now. Talks with Mark Chapple lead us to believe that there is too much timing going on for the heavy fueling, and as such, we're seeing a drop in power. I have my suspicions (and Mark ain't talkin' ;D) that TST has recently bumped up timing a bit.<br><br>So for the very high power crowd, you're left with a PM3 Competition (160 HP), Edge DRAGComp, or Blue Chip FMS Deluxe by themselves.<br><br>Rod
