What are the advantages of a DBW on a turbo engine?

My M3 turbo had DBW,removed DBW, I can re-install it but is it worth the hassle?

Any Syvecs users with DBW on a turbo engine?

Every GTR kit still uses the OEM dbw, and it has a lot of advantages.

Massive range of idle control via throttle, cold starting and fast idle till warm not a problem.
Variable throttle response can be tailored to suit and multiple maps available.
Throttle limiting on launch and at low speed
Very effective ALS available.
If using a sequential box then downshift blipping requires no additional hardware.
Valet mode can limit throttle use.

When driven properly by an ECU with good control, it's pretty much as responsive as you need, the only time it can let you down is when you want to lift off at high RPM and boost and the very slight delay can need a little work.

As pavlo said, a lot of good feature can be add with a DBW system

A lot of people are actually fitting DBW system on non-DBW car for the versatility you can obtain with the Syvecs

Yep, I now have DBW on my 1996 Single turbo Supra using a 102mm throttle from a Corvette IIRC.
