Took of my original sparks and checked them to see if they had increased in gap, found 2 at normal eg .70mm but the other 2 >0.75mm almost 0.8 mm, also they were so freaking tight as well had a couple of goes at a couple of them to actually take them out. Installed the new ones, checked again for any loose hoses and everything was tight, installed the TMIC and took for a drive to the missus when i came home decided to WOT in 3rd went to about 5500 rpm and the car felt amazing (lost a bit of traction as well) and barely any knocking present max was 0.65 and boost was at 18.2 psi but i forgot to log it grrrr. So fingers crossed that it may have resolved the issue.
