I've been playing with the settings on mine and it seems I'm getting the best mileage on #3 with timing on 4 (fuel economy according to directions), and the rail pressure on stock. Still messing around with the settings.
The REVO TNT is probably a little too much for my truck right now.
So far, straight level 3 (Moderate Tq) working pretty good, the results are out as of yet for bumping the timing up to #4... Initially, it looks like it drops EGT's a bit, but I'm kinda unsure if there is a fuel mileage benefit, and I'm also a little worried about Cylinder temps and heat soaking the pistons under load.
