Just got it loaded, what is your afr at? Had it even learned the e yet? How much 93 was still in tank when you added the e? Lots of questions here. But the flex / e tune is a different animal makes these cars way more fun. Proof is in the pudding. Whether dyno or track the e numbers are far better. OP you are good with just a flex unless you end up going with a dedicated e tune too. The peak numbers are the same a flex but the timing will come in earlier.
I think this is a base tune only
According to Lund, this is a no flex base tune. I’m running nothing but 93 octane. I was thinking maybe the car had to learn. I don’t know. I just know the car lacked the punch at 4-5k and felt overall less responsive.
Mine is an A10 daily as well. I only cycle in 91 occasionally for maintenance. It's a night and day difference and can't wait til that occasional tank of 91 is empty
And Shaun @aed is a mad scientist knows these cars in and out. Great to work with remotely even better if you can actually dyno tune with him in person.
If you get the LUND flex tune, it already maxed out 91/93 octane (within reason). The o2's use Ford's adaptive octane logic that LUND alters slightly to run E20 and up. So you might as well get a flex tune.
But some of us don't want blowers.. you know, cause a 10 second NA car is more impressive than a 9 second FI car.
