stock tune problems for 320 B48 enigine

Hello,

Here's the story. I flashed to bm3 stage 2 and sent logs to PTF. They asked me to log stock tune too. I did it. And the results are really surprising.

The only mod for my car is a hf air filter and hfc 200 cel downpipe.

stock tune:

I use 95 gas here which should be equal to RON 91 in USA. I guess the gas quality must be crazily poor here.

Just run higher octane fuel you'll be fine. I'm from India, we have the same fuel quality issue here. I run 99 RON but anything >=98 RON should fix all your issues.

Where is here? 95 is standard in UK
