So after my disappointing search for more boost on the rollers I decided to do the 'Telephonewire' mod that involves 2mins worth of work to re jig some vac hoses. I am now getting a solid 1.1 bar on the primary and 1.2 bar on the secondary . Hard to hear if there is any detting as all I can hear is induction lol buts is super smooth thats for sure. Booked in next Weds for a power run to make sure all the fuelling is correct. Fingers crossed!
