Okay so little update. I've finally had a chance to drive the car, it spins 3rd easily which is pretty funny.
Just need to change spark plugs, it's got iridium plugs in it at the moment but the gapping is too high for the boost the car is running and you can't re-gap iridium plugs. So I'm just going to put some regular heat range 7 plugs gapped at 0.6 and it should be sweet.
