well I have tried running the 10psi map for the last 2 days and it feels great but 4000rpm and over it sh*ts its self,coughing and spluttering then runs rough !

any ideas guys, maybe valve spring issues ?

how about I modify the cat ?

the 8psi runs smooth by the way.

interesting?????

yousure its not the valet map?

although its suposed to stop you at 3000 isnt it tuner?

"yousure its not the valet map?"

Yeah DW pretty sure about that !

it pulls real hard then pop its all over !

like I said the 8psi is smooth as !

oh havent tried the valet mode.

You will find that your problem is valve spring related

or 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

ok thanks ST,I will get the plugs checked and see how it goes.

oh just ignore my pm ST

10psi do you really think its enough to cause a problem?

pretzel ran that and a little no probs, the others ive done havnt had a prob with std gap at those preasures?

just get them to check mixture and etc on the dyno too!

a dyno run is on the cards as soon as I can get it done,bloody holiday season eh.

how about a better flowing cat,that would ease the back pressure a little ?

10psi with my T has no problem at all ask the two ricers that had no chance

Merry xmas everyone

Just 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
