    I just looked it up, and on average, Chevy tunes for low RPM torque, allowing for greater gas mileage (~+5-7MPG), and does mostly small engines,
    while ford tunes theirs in the higher RPM range, allowing for more torque and HP, but with a little more lag.

    For the Fiesta ST, the 1.6 liter, even without the turbo is good enough to pull the car pretty nifty.
    In Europe they actually sell standard fiestas with 1 to 1.5 liter engines (non turbo).
    So the 'lag' is mostly unnoticeable.
    If GM would have built the Fiesta ST with an Ecotec engine, they would have it kick in around 2k RPM, top speed of ~120MPH ~175HP, but with higher torque figures across the line (flatter torque response).
    I would guess this would be the case.
    The 1.0 is a turbo.

    A quick search did not reveal what you’re claiming. So, let me ask you this... Can you quantify those claims?

    Define normal acceleration by pedal % at a load (we can just use gear at rpm for ease).

    Because I can apply 10% pedal in 2nd gear, call it “normal acceleration” and produce X boost at X rpm. I could also be in 5th gear and apply 10% and produce much more boost than in 2nd gear.

    I assume you’ve got datalogs from your Cruze to back up your claims? Or are you just making stuff up?

    Given his stellar credibility thus far, I think we all know the answer to those questions.

    There's no real 'treshold' where the boost kicks in.
    I just rate it where I start noticing the boost. Butt dyno, if you may.
    Below 3k RPM, the FiST doesn't really boost, unless I press the pedal beyond (about 25%) where the Sound Symphoser box starts making more noise (another one of those things where there is no real treshold).

    Just in case you didn't know how to google 'ecotec vs ecoboost', I did it for you:
    http://bfy.tw/I9JA

    First result is the article I mentioned before.
    You will have to click it to read it, just in case you forgot to do that before commenting that the search didn't reveal anything..

    You can thank me later!
    Yeah, I read that article actually. They don’t discuss the tech that goes into them. They talk about available engine sizes, configurations, basic turbo knowledge and what engines go in which cars.

    Also, if you don’t have a boost gauge, or are logging in some way, how do you know where boost is coming in?
