I didn't say it was how it works with Subaru's of the past but it was one of the first thing our group checked a year ago. This car is Subaru's first DI, the highest C.R. street Subaru boxer sold, the stock tune is uh different.
I hope I am wrong wrong but every car around here resets to 0.7 IAM after ignition off. We just assumed the 1.0 IAM was so Subaru could claim 200hp.
