looks like figures are from 91 octane

hmm, I read the 3.0 was DI only like the 2.3, but this chart says different.

That chart is wrong. DI only. There's another thread floating around with this topic from last year and it was a doozy lol. You can literally go out and look at the engines now since a lot of 24MY Ranger's have been delivered and see that it is DI.
