Thanks chaps , gonna spend a lot of time reading and researching into o/s tuning , it's all very new to me and opened a whole new dimension to working on my car , I,m just resisting temptation to plug in and start flashing until I'm 100% sure of what I'm doing ,
Think I'm going to start with some very small steps first and leave the s/d until I'm more confident Because from what I understand there is a larger potential of a major **** up with s/d
