Anybody with a boost gauge and vnt turbo should be aware of boost levels.

A boost gauge may be the best thing you could do for your turbo, You can see over boosts and no boost problems and anything in between.
K03 is a wastgate turbo and it makes a boost spike, with VNT this spike is much lover, because actuator can regulate boost much more precisely.
