Just Dyno'ed my SS VZ but just doesn't seem right. I recently bought a new 2006 SS Thunder Ute. It has the 6.0lt engine, Auto. I had it fitted with a SSI CAI, Extractors and Remus exhaust. Yesterday I also had a 3.73 diff installed as well as having the computer retuned. My HP was 281.7 at the wheels. Does this sound right? The reason I asked was that someone else had posted that they got 302hparw on their stock SS Thunder Ute ( http://forums.justcommodores.com.au/showthread.php?t=34595&highlight=dyno ). I can't work out if they are wrong or if my car is not producing what it should. I have attached my Dyno sheet.
