To drive to 2.0 litre Ecoboost engine you would be very hard pushed to feel and perceptible "turbo lag". It feels like a larger displacement engine and throttle response is very linear. It really would make an excellent engine for a Mog. However it would encroach into the performance envelope of the 3.7, albeit without the lovely noise.
Please note, I was not involved in the development of either the 2.0 Ecoboost or the 3.7 V6 in any way at all, honest wink
