Log your O2 lambda readings and convert them to AFR to see if it is anywhere even close to what the LC1 is saying, just as a reality check to see if the LC1 is reading properly.

you need to recalibrate the wideband and then log and see if the numbers stay the same or not

You know that 1.3 bar of boost is only 18.85 psi, which is lower then stock??

Maybe you should read one of my how-to's on controlling boost with ECUflash and the stock boost solenoid.

my boost in stock was 0.9 bar (1.2 overboost) i dont have map sensor and i am using gauge to monitor boost (i know that is not right) i have used your guide to add 1.2mm restrictor. and after that tuned wgdc to make wanted boost .and your "how to " was verry usefull for me ! thanks !

word. You car was boost only like 12-13 lbs then when it was stock. Stock boost on the evo 9 is 20.5 lbs, which is 1.4 bar. Most raise it to about 21-23lbs. 1.5 bar = 22lbs.

In addition it's a good idea to log AFRMAP just to see exactly what fuelmap cells your using. The value can easily be converted to AFR (X/1881.6*128). The temp and baro usually changes there too deviating from map even more. And lastly, a brief AFR dip near peak load will not hurt HP at all and in fact will provide more energy as pressure (CO combustion) than heat, theoretically allowing more turbine input
