David I have thought about the SU's but I live in the middle of Houston. For my situation the Stombergs seem to give all the performance I have much chance to use especially after I removed the secondary set of throttle butterflies. I have never driven an E with the 3 SU's so perhaps I don't know what I am missing. If I happened to stumble across a set up at a reasonable price I might go for it but am currently satisfied with the way it runs in original form, especially given the cost to switch
