Street Tuner Member 727 Member For: 22y 8d Posted 27/12/04 02:45 AM Share Posted 27/12/04 02:45 AM (edited) You will find that your problem is valve spring relatedor possibly due to spark plugs that need closing in their gap (to around 0.8mm)Haven't seen a valve spring issue on the 10psi map yet though Edited 27/12/04 02:47 AM by Street Tuner Link to comment Share on other sites More sharing options...

dave m Member 15 Member For: 21y 10d Location: secret harbour western australia Posted 27/12/04 04:49 AM Share Posted 27/12/04 04:49 AM Merry xmas everyoneJust to let you know recieved my edit on xmas eve . Tried the 8psi boost found as the other guys a lot more power right though the rev range. The idle is smoother but seems to run a lot richer on start up . The auto up changes are a lot smoother . I then tried the 10 psi boost and wow . the acceleration is brilliant the other thing is you can hear the turbo screaming from about 3000rpm with wot .The idle doesnt seem as rich as the 8psi setting, but on start up the idle speed has increased to 2000rpm ,its like you start up with your foot on the gas ,then drops to around 800rpm . . The only puzzling thing is the in the instrucion sheet capa states the kws for 8psi as 300kws and the 10 psi as 350kw is this right ? I suppose the only way to find out is to get it dynoed After running a tank of ultimate I found the fuel consumption has increased but that could be the way I have been driving ,its about 12.5 klms/ 100ks , I was averaging 11 before the edit Dave M Link to comment Share on other sites More sharing options...
