They do tune slightly different from OS, so be prepared.. Once break-in is done, set Idle gap to .5mm. Adjust LSN until you have a consistant idle that does not drop off. Drive it around the track, to adjsut HSN for good consistant speed, until you find you get no more performance, and dial it back 1 hour.. Bring in and recheck Idle, Idle should be good still but if it is a high idle, or is dropping off you might still need some adjustments..
Thanks Scott i believe the idle gap is set from factory am i correct in that? It looks pretty small compared to an os that is normally at 1mm, i double check with calipers before break in but i think i am good. i am not a big fan of touching needles until the motor has let go of at least 80% of it metal pinch i use my radio to keep in idling, also it is the five port as it has the grey case. I also purchased a weeks B2 to have with the disco i believe these two engine should compliment each other well. From everything i have read it seems that you do not want to touch the idle on these engines just use the LSN for idle speed and hen for overall power.
