Paging Derty, my tune info...
Use TR6 plugs now at .033, bt am switching to TR5724-8 at .30 later. Plugs look clean, and timing mark is normally down at base of ground strap.
PPL say if I lower my AFR to around 11.1-11.5:1 and decrease timing to around 20* I will see a big improvement. I am curious so I might try it, seems I am losing more than gaining after this cam, could be bottle pressure, as I remember discussing this issue with you before. Will order a hotbox in about a month or so.
Thanks,
Charlie.
