Hi everybody!
I've got Opel Signum 2005 1.9 CDTI (150 HP in stock) (EGRoff,DPFoff) with chip nearly 190HP. But something wrong in new firmware . The car has good accel. from 1200 up to 2500 rpm but silly accel above 2500. So I decided to check what can be wrong with firmware and make some changes if it will be necessary with your help. Can u recommend me hardware for my car? May be MPPS or something else?
