Steve, I dont have a contact number for phil morris but i think others on the list might be able to help.I think he was doing some work at motec.No i dont have an adjustable cam sprocket for the L series but ive allways been lucky enough to get them dialled in near perfect with the factory adjustment.But the chains stretch pretty quick.I reckon you should see some benifits of a larger cam with the bigger turbo especially when running more boost.The larger turbo wants to push the max hp further up the rpm scale but the standard cams can tend to fight this causing a narrow power which is an area that phil morris and nizpro worked on with a camshaft allowing the motor to produce 420hp at around 7800rpm.I also think that the 350-400hp mark makes for a good all round streeter especially when its reliable.
