Oh, I believe it's not that simple

Full throttle shifts on a manual is nowhere near the same as an automatic shifting. On a manual with full throttle shift (ie: Hondata), once you clutch in, the engine is not under load (free revving). On an auto, there is constant load between shifts and thus, keeping consistent acceleration free of turbo lag (or preventing turbo decel. and re-acceleration between shifts). The engine is constantly under load in an auto.

It's all about budget and preference. The truth is that you can go fast using either transmission. I like both, so that is why I have both on different cars

When I was talking about the full throttle shifting I was thinking of the way AEM EMS does it.. You can use rev-retard and keep the turbo spooled or spool it higher between shifts..

I agree but that is very minimal.
