Can you post a pic’s of all four of your plugs, Spark-plugs reading is a bit of an art but the basic’s are easy to tell like overall richness and if there are hints of detonation and the severity also if the plug is the correct heat range
There are a number of things that could cause a cylinder or two to over-fuel or under-fuel, like the intake manifold, Fuel Rail, Injectors and boost to give a few examples.
Also to all the guys that have Walbro fuel pumps please remember that you car will start to overfuel it been proven on a few forums in the states that pump seems to overpower the stock Fuel pressure regulator resulting in an increase of fuel across the board this does not happen to all FPR’s but it’s a very common occurrence, Why I mention this is because this could also result in over fueling
