Hello guys,
Car is Volvo V70 1999 p80 2.4T 193KM AWD B5244T with electronic throttle.

I would like to ask about advises for ME7 ECU Tune. I would like to read the ecu by MPPS v18.
Then can you give me some best free programs to edit file?

I want to increase boost pressure to 0.8-0.85b and make better AFR on WOT about 0.82, and 0.9 on partial throttle.
I'm starting with it but i would like to ask if i change AFR target there is no need to change fuel map, because ECU will hold the AFR target?

I know that i need to change LDRXN KFMIRL.


Can someone give me few advises how to make it properly and safe?
