What to check next for MCF?

MAF Sensor - replaced with new
EGR Valve - cleaned thoroughly
Hoses - checked at garage for splits / leaks

Still whenever the car is revved above 3.5k the engine management comes on

Diagnostic came up with 1 fault, the sensor so I replaced that as mentioned. It' 50 a pop and half a day off work so would rather do some more checks / clean ups or whatever before going back

Just passed MOT on emissions without any problems at all as well even with the engine management lit

Thanks for any ideas

Sounds like a boost pressure problem to me. What are the codes you are getting (P0235?). What hoses are they checking?
