AFAIK throttle mapping linearity can be easily done. It had been done in OFT tunes, so assuming that competent ecutek tuners can do it too.
As for throttle dip .. if you want to keep engine in powerband you'll be above it anyway, and in normal easy driving along the traffic most of the time i'm below it. Until i first read about existence of such, i didn't even consciously noticed it myself. End it's not that car doesn't accelerate in dip, just does it slower. But ocasions, when i need to accelerate from 2Krpms to 5? Rarely happens. When i need quick acceleration i just row down few gears anyway.
Now for general throttle lag .. if it is left as only issue .. to me it certainly is not of that high priority, especially to think of engine replacement "to fix". Nice to have it improved, but can live without.
