EcoBoost baseline power numbers

Take graphs (dyno results) with a gain of salt. Often the RPM scale is wrong, and depending on how they load it, the torque curve will be different. The gear selected will give a differeng looking graph. Dyno graphs are good for generally speaking and comparing before and after mods, that is all they should be used for.
It appears they didn't step on it until 1700 rpms, which the turbos would need time to spool, I think they climb pretty well.

But typically it really isn't a big deal how much Tq/Hp are down between 1700-2500. And like he said most of the time they are spinning the engine in the appropriate gear and it doesn't even come online until higher RPM's, and if it does down low there is lag which there wouldn't be if the engine was in a gear cruising up a hill with a lot of resistance on the motor.
Heck, I was amazed this weekend that I could drive on some country roads that had a good 4%+ pitch and it never came out of 6th gear and was at about 1800rpm @40-50mph. And it wasn't lugging at all, just smoothly crusin along. If it didn't have decent torque down that low it would have never made the grade that easy without downshifting. And i'd never had this happen in any other car/truck i've owned on the same roads.

I have 3.73's and that's what it was running and I had the gear selector set so I could see what gear I was in. It changed by 100-200 revs depending on the speed but it was roughly 40-50 mph and the rpm's were around 1500-1800. I don't think it's locked up either because I know what you're saying. I'm running about 2100 at 80mph.
