I'd like a Forester XT, but the poor road that I live on would destroy those 18" wheels, and my back. The lack of a manual transmission option is also disappointing.

Enjoy it!

Performance car ....

With CVT

Why the short OCI?

Short OCI was done in order to gauge the sample with the tune in place. That 40 looks 30 to me and in only 870 miles. Could it have been a 20 in 1700? Who knows.

Ah, didn't realize there were dyno runs on this when I saw it earlier. Typically when an oil shears it will thicken back up.

I think your tune is pretty good though based on the stock FXT DIT UOA's with high fuel dilution on the Forester board as well as some nasty uoa's on the '15 WRX posted on nasioc. I think the highest fuel on nasioc was on a WRX with a Stage I AP OTS tune. A stock Foz posted on here and the Forester board had 6% fuel with Blackstone.

And comparisons on the same sample between Blackstone and Oil Analyzer's Inc results have OAI showing fuel 2-4% (IIRC) higher.

I REALLY wish Subaru would have gone with a DCT, but I guess they have to be quirky. They should have gone with Toyota's DIT tech like they did in the BRZ/FR-S as well.
