I've got an Ecoboost 125ps for around a year by now, and I'm still struggling to drive it "properly".
I come from a Honda Civic 1,8 Sport 2009 - in that car I'd overtake by tossing it into 3rd gear and flooring it, somewhere around 6k rpm I'd shift up and floor it again - worked like a charm (I prefer to overtake as fast as possible to get into the proper lane again, and despite this sounding like I drive excessively fast, I actually don't - I normally stay within the speed limits give or take 10%)
If I do the same in the Fiesta - 3rd gear, floor it. It's pretty fast (after half a second turbo lag), but the second I shift into 4th it loses a lot of power.
Normally I'll upshift around 5.5k rpm in the Fiesta, and this means it ends up below 4k rpm in 4th gear. This in turn causes it to be quite slow until it reaches 4k rpm when it suddenly starts pulling again (could it perhaps be overboost cooling down or being disabled briefly?)
So what I'm wondering is: How do you guys make the most out of this engine?
And again: I don't drive like a maniac, despite this thread sounding like it
