question regarding power
When he mentioned air temps affecting your HP/TQ numbers, it's not just from the ecu pulling a little timing. Engines make more horsepower in colder weather no matter what. The air is more dense so more gets into the cylinders under the same boost levels. This is why it's hard to compare dyno sheets from shops that will do pulls in the winter without weather correction. On high powered cars I have seen as much as 40whp from a pull on a 15* day vs. a 85* day.

The RPM slope in runs #1 and #2 looks like there may be some slipping...run 2 especially. Run #3 looks pretty smooth though. Of course, this is just with the speed of your logging and using 1 byte RPM. It's a tough call.
ill just throw it back on the dyno when i get it back together and see what it does at that boost lol. I know its making substantially more torque then it did at cbrd now. the peak area was never dialed in there. My daily driver tune will prob be 33psi though. I dont wanna beat the turbo that bad.
would it help if i took pics of the clutch plates to show you?

No, that's not going to help me. Maybe someone else.
Putting it on a dyno will tell you for sure. The problem is these VD tools will show clutch slipping as higher than normal numbers. So, if you're slipping at peak torque, you're going to get high numbers there.
So, just throw it on the dyno, or include speed in your logs as well.

Yeah, I'm not sure. With the 1byte RPM logging and the logging speed, it's hard to pinpoint, but it looks like it may be slipping a bit in a couple of logs.
Out of curiosity though, I ran your logs through DynoVision and they seem to be a lot closer in number. There isn't that big difference between #1 and #2/#3. There is a small difference, but not as much as you posted with VDR.
I think maybe you just have a little slip at peak torque in a couple runs. But again, I'm just guessing. I would be interested to see your results when the car is ready.

Here is a snapshot of a 'slightly' slipping clutch at peak torque and a graph of the RPM curve below. If you have a slipping clutch, it beyond obvious in a dyno simulator. I looked at your 3 logs and you definitely didn't have any slipping in those 3 logs.
lol ya mine def didnt do that.. when is that gonna be rls'ed? that looks fun
Its a never-ending endeavor lol. The kid helping me wants it done before MOD'10 (Mitsubishi Owners Day) in New Jersey this year but IDK if there will be enough beta testing time. We'll see I guess. Thats just a snapshot from my excel alpha testing program, the stand-alone looks a bit different
