it still needs a mapping session but I'm very pleased with the performance especially the torque

Looks like a ton of rocks and concrete to run into.  Your pair is bigger than mine

its only when you walk around you notice how much there is to hit, the drops either side of the road are more worrying but fortunately the speed isn't too high

unfortunately i had a bit of a crash with the car. the forecast was for light showers but the rain came quite heavy and caught me out. most of the damage is panels and a bottom arm so shouldn't be much work to fix. biggest problem is when hitting the bank the air filter was ripped off and the engine sucked up loads of ground and is now down on compression so its off for a clean out, rings and a hone. shame as i stopped raining not long after and the car had been running really well

Oh mate that's just bad luck, the engine sounded strong throughout.
I did lol at the category you gave the video, if you can't laugh at that what can you do?
