But thats missing the point and is not truly like for like you are comparing different compromises. If you take a fast car and a slow one its hardly magic in announcing the fast car is fastest? Tune the slow one so that its as quick as the fast one. if one then drinks petrol but the other still uses only 70% of the diesel there is a very obvious conclusion that in that scenario that one engine is better than the other
Make them genuinely like for like where they both consume the same fuel and just see how well the diesel goes.
VAG who designed the things in the first place know that and that's how they can now make Lemans winning diesels. The best petrol engines in the world couldn't keep up.
WTF no your missing the point if truly like for like the would be no difference at all MPG or BHP the post is about a remap on a derv and the same on a petrol and the petrol should be quicker.... don't try and mince words :w4nk:
