First of all - hello to everybody 
Then I would like to ask, because I can see that there are topics about MIl and EPC errors, but I'm not very good in german, so if anybody can write me what can cause this two errors. We have a small EPC and the screen all the time, and MIL error for a second when the engine starts. It is Street version of KTM, on the dyno today it generated 219 BHP and 305 NM, so 20 BHP less then in stock version, I guess that it is because of this errors. I know that EPC is from acc pedal, and MIL is from engine electronic, but what specifically check?
thank you for your help
