That is KKK K03s like what we say... nothing to do with Garett..

With the 180 models you will find that the Cylinder head is slightly different - more like that of the 210/225 models... this with slightly increased boost and slightly different software makes the difference in power...

Thats why a 180 properly tuned will make slightly more than a 150 tuned.

got my hands on this list:

150 CP - KKK K03 max 180 CP
180 CP - KKK K03s max. 210-215 CP
210 CP - KKK K04 max. 250-260 CP
225 CP - KKK K04 max. 250-260 CP

maybe someone wants to know. the guy i was talking about from NVT thought that KKK is the same with Garret )

2001 onwards (approx) ... 150 is K03s..

only older cable throttle, and the very first drive by wire 1.8T are smaller K03.. upto 2000/2001 (approx)

dates are not exact because actual build date can be way off the actual registration date....
