post your log and not your graph.... i want to see this "no knock" with a dip in power that early in your graph. If there is no knock, and you have that.... you may need to hit up another 15hr session

because genius, you can make a car faster all day long, but at the expense of safety is not the greatest idea in the world. So when you do a pull like that, and you see serious dips in the curve, its usually because the engine is knocking. knocking means there is some tuning that needs to be done because the car is not running safe. Since he is looking for insight, he can post his log and then we can look at it to see if he is running on the edge or running in a safe area

sorry but that whole thing is bogus to inflate the numbers... adding weight forces it to show more power, the smoothing is way too low so you're getting those peaks which also makes it show more power.
put the correct weight in there and turn the smoothing up and you'll get a more realistic number.

Here are my power curves...same tuner, same place, different car, different mods.
I'm running an IX 5 speed with the stock 15.5G turbo, stock DV, HKS272 cams, walbro 255 fuel pump, blitz nur-spec turboback exhaust (decatted) and a drop in panel filter. Runs were done on the locally available 95 RON pump gas.
Should add that my car's tuned slightly differently than dxbevo9's car - I do alot of autocrossing so i asked the tuner to make my boost hit fast and hard, taking advantge of my smaller turbo, as opposed to going for lots of high end.
Anyhow, on to the power curves, which should hopefully illustrate Mellon's point
I have 2 boost settings that I use - 1.4 and 1.8 (low and high), hence the two graphs (I use a Greddy Profec2 Spec B EBC which allows this).
Here are what my curves look like. Set 1 is with my weight (170lbs) and the 20 lbs. of crap i was carrying at the time was factored in (laptop, fire extinguisher, mechanical tire inflater, six pack of diet coke, tools, etc).
@1.4 bar:

@1.8 bar:

Set 2 here is with the "magic 772 lbs. dynodynamics dyno correction factor" added in.
@ 1.4 bar:

@ 1.8 bar:

So, am I getting the bargain of the year in terms of my horsepowerper-per-mod ratio or are the DLL numbers using 772 lbs. as the correction weight fudged slightly? You be the judge

dxbevo9 - all you need is a 20G man. You might be able to do a swap of your old turbo for a 20G at 1000 Dunes for a good price, talk to sam 
For your retune, the tuner could be coming back in Jan/Feb if there's enough interest. I already need a retune for my HKS super racing suction/Kansai box, intercooler piping kit and 02 housing combo, but the more of us getting tuned the better the chance banana will come over
