"Turbo lag" is relative.
You, being N/A, have a concept of what you percieve as "turbo lag". Me, coming from 8yrs of FI modification, feel "lag" isn't actually laggy unless full boost comes on around 5k. Full boost in the 3k-4k range is commonplace, unless you go smaller, BB, etc.
Thus, I pointed out that the teeny snails on the Rex(s) have very little lag compared to your assertation of "massive" lag.
