I've got a 99 1.8 Sport Astra and i've been told that if I load the maping from an SXI engine I can get the 123bhp. (I have 115 at the moment)
1.) option would be to go to Vauxhall and get my ECU upgraded with the new software?
2.) Could I get an SXI ECU from a scrappy and use that?
Would the 2nd option work? Does anyone know how much Vauxhall charge for re-mapping the ECU?
