Mark- opinion of Shell V power 93?
My car seems to run very well on Shell Vpower 93 and your chip. It also runs very well on Chevron 93 octane. Of course the 95 525iTU has the knock sensors that should take advantge of the highest octane.
Just an observation

Depending on how you drive, you may not notice a difference. (if you don't accellerate hard)
