Boost sag? No, you don't need EBC.

I've got a Big eBay special turbo on my 1.6, and I find that using "Point C" after the throttle body gives me the best response.
I have not seen any drawbacks with a year of use, including multiple track days.
The turbo doesn't even spool at lower engine speeds, so no issues with running the system too hard/hot with the wastegate closed at partial throttle openings.
I do agree that this would be an issue with a smaller/normal sized turbo (and that "Point B" would be the choice for an appropriately sized setup.)
When I have the revs up (past the boost threshold of ~4000rpm) at part throttle I can hear the turbo is spooled up nicely.
This means immediate boost when I go to WOT.
As they say YMMV, but Point C in my case is measurably superior to Points A & B.
