my boss has just invested in an asnu injector cleaner, pretty good bit of kit, i cleaned my injectors which i thought was ok and it upped the flow rate by about 30cc which over 5 injectors is quite alot
The consensus on the coupé forum is no. Best practice is to fill up with optimax at least once every four fills, this has added detergents to clean and maintain everywhere that the fuel reaches.
