Good Samaritan Max Capacity pointed me towards another flaw
in the stock Legacy Tune. 05-06 Legacy's add 2* to Cylinders 2 and 4 which starts being a real big issue once you start increasing the power. Subaru saw this as an issue and zeroed out the tables stock on 07+ Legacy's.
As you can see stock tune adds 2.11* starting at 3600rpm.
Fix is simple, just zero it all out!
I wanted to do test and see if any power was lost due to less timing. I did two side by side runs on the same stretch of road. To avoid inconsistencies with self learning I set IAM to 1.0 as the default and did the run right after flashing the tune.
As always take these tests with a grain of salt, I was surprised that I didn't loose any power, even more surprised it gained anything.
