Addict: Its ok man..No i dont have it yet
Do you have 0.9 spring or 1bar?They diden have 0.9 when i order it so i got the 1bar instead.They said."You have to look with a lamda to see that the mix is ok" so i guess i have to do that.
Im little affraid that my boost is going to get to high with the 1bar spring and no cat.What do you think?

Many use the 1 bar. Its generally accepted that this is OK.
To be honest, I don't know what spring is in mine as it was before I bought it. Its faster than normal that's all I know and everyone tells me. When it goes in for its service next month, I will ask the garage to hook up a temporary boost gauge to measure it.

I was testing my car yesterday. I had the 1bar spring in the wastegate and nothing after the turbo.
The car felt really fast ,but it cut the fuel(to much boost) I dont know what do do now...

Hi Burman,
You should not have problems with the 1 bar and cat bypass. I am not that technical, but have you still got the Lamda sensor plugged in, or did you disconnect it after your cat bypass? My understanding is that it is best left connected as it helps regulate the mixture. Also everyone seems to say that you should set the Oxygen at 3% although if everything is connected and works properly then the CIS settings should adjust themselves. I have never set mine, but the car runs perfectly.

As I said I am no expert so you might be better posting a new thread on your questions.

PS: Cutting out on boost might be due to a faulty Blow Off Valve, or a leak somewhere.
