OK, Gotcha, makes sense when put in that perspective. Never would have thought about the effects of direct injection. Thought I was crazy looking at those logs but like I said it has been over a decade since I've really looked at this stuff. Knew there had to be something else going on here with the fueling. If you posted a log of a FI engine with a 14.5 afr across the board it would have raised a huge red flag. Things change and this can explain why even more power per liter is possible. Thanks for taking the time to bring me up to date.
This is really a great forum!
