What are you using for weight in DLL? And how much does the correction factor affect the results?

I'm a little surprised to see that the DLL is reading that close to a DD dyno. I generally think that my DLL values seem a fair amount higher than what I'd expect to do on even a dynojet, much less a DD dyno. I use a 3000 lb. weight (I have an RS) and 200 lb. contents (I'm about 150 lbs) and don't use a correction factor (when it's 80-90 degrees out), yet it still seems to read high.

I am confused. Why did you stop dynoing in 6500 RPM and you stopped your log pull at 7200 RPM. You should have reved it our more.

I would richen it up in the 3000-4500 range and run some more timing up top. I think you will find a lot of people shooting for 16 or 17 degrees at redline.

The dyno chart is clipped after the car stopped making power.

I did make a dyno pull that revved all the way to my 7800 limited and power was very weak.

25°C
59% humidity
100.4 kPa

1/4 of a tank

I used 3300lbs for the car itself (I have a 40lb toolkit in the backseat, a heavy FMIC, and the SSL package w/ sub in the trunk)

And I used 210lb for my weight, so a total weight of 3510lbs.

Just something I want to add. Everyone has an opinion on what works to make power (more boost, more timing, or leaner) I have found out that my car gets very little of a power increase running 11.5:1 over 10.5:1 I would rather be rich, run 5* at peak torque and 17* at redline than lean it out and gain 4hp. Every car is different though. I lost power running leaner than ~11.4

That's kinda weird. It should make power till at least 7.0, shouldn't it? Are you being shy with timing? Your TQ is good thou!
