simon d2:
went to work this morning on motorway at 73mph my d2 started to loose power and come in again seamed that ecu telling the fuel pump not to give more fuel just fitted decat and mid replacement is my over modulator telling ecu to drop back? :angry:

lurch_917:
did you remove any sensors when you removed the pipe's as the ecu could just need re mapping ? for the changes.

Ricky:
Sounds like your suffering Overboost, check the wastegate arm is free moving and well lubricated, check the hose and electrical connections to the wastegate modulator

G30RGE:
Also - try disconnecting your air flow meter and try it down the road.
Mine did this and it was a faulty AFM

Ricky:
simon, if you are anywhere close to me (wolverhampton)  you can happily plug into my diagnostics
