wouldn't recommend ab chips
had an ahmed bayjoo chip in my escort power was 195@wheels@17psi
but boost just came in with a bang and it could only rev to just over 5k, car wasn't really driveable either, got an AVA chip and power was increased to 208@wheels runnin 17psi ,car was much more driveable as boost came in gradually got fuel ecu mod after that to let it rev to 7200 not had it rr since
think it only cost me £180 plus vat for chip and £200 plus vat for fuel mod
