Really? The forum is "Tow Vehicles" and the topic is 7.3 twin turbo Godzilla. That's slightly different that "Towing".

BTW, turbo lag exists. It just doesn't exist as much as it used to. If the manufacture's were smart, they'd add an electric motor that spools up the turbo when it's needed, which is powered by a battery (making the truck a hybrid).

The vast majority of what people perceive as turbo lag on a modern engine is actually drive by wire throttle programming. Unless you have a single purpose design like shoving a huge fixed vane turbo in a racing application, there is not enough lag to use as a justification between the different options.

I agree. Most of what is perceived as turbo lag is just the drive-by-wire tuning to keep with emissions regulations. The ECM will gradually build up power in stock form. I tuned this out of my old Ecoboost and it made a world of a difference.

If someone wants to find out what real turbo lag is, they should go drive my friend's 6.7L Cummins with a large S467 turbo. That thing has lag, but it is meant for top-end power not power down low which is why I went with the S365 turbo on mine since I tow.
