Tunnels & Drifts but forced acceleration

After the original "Tunnels & Drifts", the remix "Tunnels & Drifts but grass", the crazy version "Tunnels & Drifts but ice" and the shitfest version "Tunnels & Drifts but glass", the dirt version "Tunnels & Drifts but dirt", the cut version "Tunnels & Drifts but cut", the tree version "Tunnels & Drifts but trees", the checkpointless version "Tunnels & Drifts but checkpointless", the endurance version"Tunnels & Drifts but at checkpoints you restart", the mirrored version "Tunnels & Drifts but mirrored", the reverse version "Tunnels & Drifts but reverse", the multilap version "Tunnels & Drifts but multilap", the freewheel version "Tunnels & Drifts but freewheel", the valley version "Tunnels & Drifts but valley", the no-grip version"Tunnels & Drifts but no grip", prepare yourself for the fullspeed version !

The map is exactly the same as the original, with only a minor difference : you have to drive the whole map while on the forced acceleration effect (which locks your throttle and disable brakes). I expected this map to be really hard but it seems that the effect doesn't make the car accelerate as hard as the normal throttle, which keeps the map easily completable without touching any wall.
That's a special effect that can only be activated with custom item, thanks to eyebo for them.
