Injectors came back from Aks tuning Saturday morning, Cylinder 2 wasn't flowing as good as the rest so needed to be replaced to get the best out of the set.
I also de-coked the valves over a few days replaced the fuel filter and spark plugs, now the car feels more smoother to drive and starts slightly better as well.
Looks like I will be repeating/checking the valves in the next 10k from now on.
