I have just put a set of Piper Ultimate Road Race Cams,KBCOS285HT kit, with Viernier pullies.Timed them up as original car would be, tickover supurb, she is running on green injectors,280150803.Can anyone tell me roughly which way the Viernier should be altered, retard or advance, and degrees.The car at the moment has a lot of turbo lag. Where i am in South Wales, i can't find a rolling road.Regards Kerry
