Every car and setup is different and will react differently to more boost, more timing, etc. Make changes, log everything and keep checking.

EDIT: Also, I see you have DSMLink, which is a wise choice. If you need help depicting the logs and deciding if more boost or more timing or whatever changes you made were beneficial or not, the DSMLink forum has a ton of really intelligent and helpful people that will give you a hand.

I know but do you have any estimate ? I will do the fine tuning after that .

The thing I will do is to keep the stock timing and increase the Boost until I see some knock .
I will keep my A:F ratio around 11.5:1 with my Wideband .

After I see some Knock I will Reduce the boost by 2PSI and start Tuning the Timing setting


This is the Good way to do or Im lost ?

Sorry For my poor english . Thanks

You have the right idea. Keep increasing the boost 1-2 psi at a time until you see some knock, I'm guessing you'll start to see some knock around 23-24 psi. Can you post some datalogs?

Evo 3 gt wow thats brave.. everyone that ive talked to running that turbo won't take it over 15psi because they are afraid that it will break.
