Speed Passion GT 2.0 LPF motor limit

[Charger]

Hi everyone, I have a Speed Passion GT 2.0 LPF and was wondering if I could run it with a 5.5t motor in a touring car with timing advance, turbo etc without blowing the speedo up.
I know it says in the manual that it can handle down to a 5.5 with 6 cell/2S but I'm not sure if this is meant for a different car e.g a 2WD buggy or if it's only supposed to be ran with zero timing.
