Audi_TQ used to with an unchipped ECU, it seems he's made up his mind though...
...as he figured that he was getting no real performance increase only by increasing boost...
and a boost controller on a chipped ECU is pointless, unless the chips are crappy, otherwise the chips should do the same work, and even better, because a boost controller isn't adaptive WRT knock sensors and it also doesn't have any intake temp related boost control, which the stock ECU has and which can also be reprogrammed. And for a car that runs a stock turbo, not to mention the altitude compensation feature that allows people not to overspin the tiny (yet pleasant and reponsive) stock K24 turbo.

Mihnea

just one pressure switch and 3/2-way solenoid valve
if the boost control is your only goal, this one does it. and won't cost your arm and leg. we're talking about less than a hundred bucks.
as Mihnea said, it doesn't have the luxuries that ECU and chip have, like temperature and timing variables. it also cannot regulate the boost according the RPM which i consider as the biggest issue. stock turbo can't handle even 15psi of boost at 7000rpm. it's out of range and produce more heat than a healthy boost.
more advanced boost controllers like the ones Apex does, can regulate the boost according the RPM, but also the price tag is something you better use for something else. good use for the money is to save some for a good turbo. for the one which is able to supply 20psi of boost at 7000rpm.
IMHO, the boost controller alone cannot make a big difference, unless you find a way to control fuel and timing as well.
