A few more updates fitted in the last few weeks at 72,400 miles.
New Air filter fitted
New Wideband O2 sensor fitted, it wasn't flagging up as defective but after investigation it seems they have a lifespan of somewhere between 60-100000 miles. I changed mine as I know the egts are high on the lcr and will knock the stuffing out of it. I am glad I did as it completely changed the character of the car and I think it will repay itself in terms of MPG and engine safety!
Fitted a blueflame exhaust and scorpion decat pipe, along with spacing out the 02 sensor with washers (will see if this works in the summer). Not very impressed with the fitment of the blueflame it hangs low at the rear and potentially fouls the subframe tunnel, but to be fair I am not sure if this is decat pipe throwing it out of alignment. Sounds good initially a little raspy but as it carbons up this seems to quietening down, spool up is quicker and the engine seems freer to rev!
