it will be ok for daily driving but if it was mine wouldn't be hammerin it til its proper set-up
if you change any characteristics of the runnin of the car it needs set up afterwards to gain its full potential
remember grs has a pressure drop of upto 4psi so your turbo is workin harder than its actually showin on your boost gauge,addin a pro alloy raises boost pressure so i'd get it set up as soon as you can mate
