Saw that to, but that was there second run after a cool down period, but when the run was started ECT was 176 and by 5k was 180. Yes the early knock was really odd because I never had that on many street pulls before the dyno session. I later found my Boral resonator case split at the top a little and was likely causing some rattle early on, but this did not affect peak power because it clears up and runs at 0 knock from 6k up and full timing.i'm not a log-reading expert, thats @markmurfie , but from what I see...
1. Your ECT is pretty low in the 160s at the beginning of the pull. If the car is too cool and not fully up to operating temp your numbers will be lower. (Had this happen to me). Did you only do one single pull on the dyno or another identical pull after it was warmed up more?
2. You had some knock in the midrange which could be the cause of the peaks and valleys in the curves.
3. Not related to low numbers but from what I see it appears your knock sensors arent configured "correctly" in the typical way these cars are set up. In the fact that your knock is reading 0 and your base timing is 22. Usually base timing is lower and the ECU adds timing via negative knock. Surprising to see PBD set it up this way.
Take all of that with a grain of salt since I read logs in excel lol. Hopefully someone more knowledgeable can chime in.
