Boost controller ?

So far I've had a Blitz nur spec and de-cat fitted to my VIII, will this have affected the boost pressure? If so how much and should I be looking at having a boost controller fitted?
Thanks.

it will of increased slightly due to the open pipe working properly and extracting the gases!
a boost controller will give you more not less!

A possible increase of .1 or .15 bar mate..

I have my AVC-R and have 3 settings:

Off - 0.8 bar max, holds 0.7 bar
A - 1.25 peak, holds 1.2
B - 1.1 Peak, holds 1.0

Don't think that running less boost will give you much better economy because it won't

Most I've had out of a single tank is 225 miles.. Think I was running on air for 30 odd miles though
