The hope is slightly less boost, but a reduction in restriction to make some of the power back.
This likely won't be the last combination so an intermediate step at least for this upcoming season.
Bad idea?
Note: German restrictions for inspections and checkpoints dictate a stock appearing car...
Thanks.

There are so many upper and lower pullies available that you should be able to get the boost you want
