Revo sps2 95ron loss in power ?

[Cronogr]

hi, guys i have an A4 1.8TQ B7 (not a b6) and i recently bought a revo sps2 so i can use the anti-theft function, also i changed the setting for 95 octane fuel (since in italy they don't have 100octane) i notice loss in power the car just doesn't feel right, when i change back to 100oct the car feels better, what gives ?

p.s. after i got chiped i didn't remove the sprint booster, from revo they told me now it's useless, maybe i need to remove it ?

The 100oct setting will give you more timing. You should run some CF logs to see if you're safe.
