The red lines end before the blue lines.

Does this mean that the pulls were in different gears?

In other words, they hit the top speed limiter doing the stock baseline, but did not doing the PBD custom tune. Also, notice the peak hp figure is at a little higher rpm in the tuned version.
its because of the raised red line stock stops around 7500
tune goes to around 8000

Both horsepower peaks are below 7500.

The stock run stops well before 7500.
yes but wheel power is still more without shifting enabling you to hold the gear longer and have more power at that speed compared to stock

Sorry, I know this is written in English, my native tongue, but I have no clue what it is you are trying to communicate. Could you try again?

video explains it best
every time you shift you are losing power
holding the same gear longer means more usable power
dynos correct for this but in the real world you notice lower gears give you faster acceleration than higher gears

What does that have to do with the price of tea in China?

Car is daily driver A10. Only mod, AWE cat back. Also, only did intial drive in traffic. So butt dyno says you can feel low end torque. First noticed going out of drivewayx, then when passing. I messed up and didn't do any timed events before install. Plus there are driving modes to go through as well and checking out shifting. I'm not going to be doing any other mods or E85. Getting ready to do last data log for them, 3,500 to 7,500 in ,4th gear. Trying to find a good road where I can do, because this is about 44mph to 100mph, plus play with phone which TDN datalog software is on. If you look at the dyno run, there is a lot of meat up top as well. So, for $684 (w tax) total, its an option. Sale ends 31 March, and I have not seen HP Tuners RDT4 be discounted recently, so $460 for HP and $220 for tune.
Nice! Please keep us posted. Looking forward to hearing more! Im definitely considered this, I'm just not sure about raising the RPM limits. I also want to get the top speed limit removed and maybe few other tweaks not sure what's available.

Just confirmed 8,000 redlne. It appears throttle response is very noticeable in normal mode (from throttle and tune). Will check other driving modes. Seat of the pants feeling in other modes, more giddyup and go at peartisl throttle. When I went out to practice 4th gear data log, I was surprised at how quick it accelerated and the fact that it hit 100mph in no time. When I do actual data log, I'll try to get a time.

Nice deal. Mine for 93 only tunes including the RTD4 and 4 credits is $999. I do 4 tunes. They are for sure eating almost all the tune cost at that deal. Glad you like it. PBD knows their stuff.

@ZXMustang I am new to this. Is the RTD locked to a tuner or I could use it in the future with another tuner?

Installation was easier than i expected, but your dealing with HPtuners first and then Palm Beach Dyno. I set up an account with HP tuners and downloaded their app on my phone. You buy RTD4 credits from PBD. Once PBD sends RTD4, you have to sink with app, then copy your factory tune. Email PBD and they download your tune and then load their tune on app. You then load PBD tune to car. Your orginal tune is still loaded on app if you ever need to go back to stock. Hardest thing was to datalog for PBD, idle, cruise and WOT in 4th for A10 to 8k rpm (like 44mph to 90). So problem was finding a road where you coild do without traffic and also avoid a ticket. Most notable delta is in stock driving modes. You feel the difference immediately. Not to say that perf is in other modes as well. Going to ask PBD if the fuel, timing, cams changes are the same in all driving modes or not.
