Cry Like A Baby Problems with my 2.0 ts (performance)

Ok people,wher shall i begin.
Recently i have changed the oil, spark plugs, installed a BMC CDA, MAF, lambda sensor and still my car lacks a bit on performance and idles not very well.
I have just put the original airbox back on and sealed the lid with some silicone but this has made it worse.
The only fault that Alfdiag is showing is the speed sensor is not working.

Does anyone know what else it could possibly be or something i can do?

hows your exhaust? I've known exhausts to breakdown inside and causing an obstruction inside restricting gas flow

how long has the bmc been on, it can take upto 2 days for the ecu to configure itself to the new air intake. the prob lies with the filter as u said the old box is making it run even worse, put the bmc on back onand go for a good drive so the ecu can adjust itself. check that you have no splits in the air intake pipes as this seems to be a common problem.

A blocked catalytic converter would cause the problems you describe I think. Also have you cleaned the throttle body? although that would be more of an issue at idle if it is dirty.

Does the car pull evenly all the way to the red line? Maybe if someone with a similar model lives close by you could do a performance comparison (safely).

They are a heavy car and do need a few revs to liven up. At least the 2.0L cars do. I have no idea about the 3.0L.

Good luck

all the rubber pipes are new with no splits. I have also had a new stainless exhaust fitted so i know it's not that. The car tends to perform better when the engine is cold but when it is warm the revs at the high end tends to take its time getting to the red line.
I'm thinking it might be the ECU as there is a fault on it all the time saying something about the speed sensor,whatever that is.

maybe disconnect battery for an hour + , ensuring you have radio codes.

then go for a long hard drive and see if the ecu settles in.
