So with a new loom and a coilpack upgrade it should be 100% but all things are not a easy as that lol sensors which are gapped must me good and within spec and also the mechanicals too a worn dizzy shaft can cause gap issues with the phase sensor etc etc

Make sure your loom maker knows what spec you want ie wasted spark this will save unessesary multiplugs and will make installation easier
