car: 08.5 MS3

I have included a couple of logs (From AP).
Running Stage1 stock vehicle map v1.03.
Stage1 for Stock Vehicles. 93 octane fuel.

I know..they are not graphed but deal with it.

I am running 93 octane fuel.

Also, what the difference between actual & equiv A/F ratio.

The car feels damn quick but kind of nervous about that lean spot when I hit boost.

Considering running the stage 1 stock vehicle map for 91 octane to see if it richens up the mixture.

Logs 2 & 3 were WOT..not sure what gear.
Log 4 is partial throttle not sure what gear.
