But I set Start boost setting to 40%, which means 14PSI. I don't know why boost is higher. Should I set Overbost limit to lower PSI (I left fefault setting - 17 PSI)?
I know how to check my boost, thanks
A strange thing is my car used to autotune to 16+ PSI with stock turbos and to 18+ PSI with RB turbos with the latest autotune maps...
I read many bad things about E85 and 335i ~1.5 years ago (bad for our engines, fuel lines, fuel pumps, etc.). That is why I don't really want to go with E85. Plus, I should do many modifications, right?
Thanks for your help.
