On the VIRTUAL DYNO run in blue what would cause the large dip in power between 4500-5300 rpms? It's possible I was going up a hill I guess but I don't think so. he blue run has boost turned up about 1.5 psi over the other two, and they were all on different stretches of road.
My current thinking is timing must be the culprit?
I attached the tune/log graphs of the blue run as well.
Why the dip.
Re: Why the dip.
AFR and MAF dont dip there so the motor is taking in the same amount of air/fuel. Is your knock sensor active? What is your actual timing during the pull? 16° Steady?
Do more than 1 run if you want to compare two different scenarios. 3 of each would be best on the same piece of road, same direction, on the same day. Otherwise don't try to use it to compare. The wind blows, or the road dips, your engine looks like its low on power.
