Not much has changed since the baseline runs except the temperature 10 degrees lower, 500 more miles on the air filter, tires 2psi lower, and different tank of fuel (although from the same station and with the same concentration of additive).
Peak numbers are:
Before/After
hp: 159/189
ft.lbs: 347/386
For gains at the peak of 30hp and 39 ft-lbs, which is right in line with Inmotion's claims. However, there's an area around 2600 rpm where the gain is 60 ft-lbs! And down at 1800 rpm the gain is still a massive 50 ft-lbs! In fact, the lowest gains were seen at the old peaks. The curves are just dramatically fatter and flatter from end to end.
Here is the graph of runs after the tune:
Here are the before and after runs on the same chart. The vertical line is just showing numbers at about the power peak. Compare red to blue for before and after, respectively.
Even if, as mabelaker suggested in the original thread, you remove the roughly 20% SAE correction factor and subtract new vs. old numbers, you end up with gains of 27 hp and 37 ft-lbs at the peaks. The rest of the rpm range there are substantially higher gains. I asked the tech to email me the .drf files, so we'll see if he comes through.
I took some video at the rear of the vehicle during both sessions to compare visible smoke. There is definitely more after the tune, but it's nowhere near obscene. In fact the only reason you could see it was because the floor was white and the vehicle was sitting still. The air/fuel ratio dips to 14:1 at the lowest so there's still room to fatten it up once I beef up the torque converter, injectors allowing.
Overall I'm really pleased with the tune. It's a real joy to drive, and you can't beat the gains for $300. Inmotion's service was great.
