hi，The stage 2＋ of the 98ron map and the 95ron map of the horsepower is the same? Or there is a difference, how much the difference in how much horsepower。Or any map can be 400P in stage 2＋？（N55 PWG）

Insignificant difference. Try both and find out. I have done plenty of pulls with 95 on 98 map. The engine is very advanced and will just retard timing with lesser octane. No need to worry.

Because China's No. 98 gasoline is very poor and unqualified, so I should not have problems running the 98 map？ Is it better than the 95 map?

I also live in China as you can see. I find that 石化 and 石油 has good quality fuel but no big difference between 95 and 98. I just run 95 with methanol injection.

Do a log with Stage2 95 map and 95 fuel then you can see if good or not.
