Hi GLJ My 998bip has S/R cams, 996R ECU, full 50mm system, so it's similar to an "S" as it stands. It's going to LouigiMoto in Bristol next week for service and fettle, including: Set squish Gas flow heads Skim heads for 12.8/1 CR Custom mapping PC111USB I'm getting dyno print-outs for before and after and will let you know the results.
