hello.i had this remapped on stage 1 as to me it used to be gutless compared to how it looks.initially its made a lot of difference to both acceleration,engine sound and for some reason more economical too as it was only doing 18mpg at worst.
however the speed and difference in engine soung which sounds like the turbo whoosh is not consistent and at times the car drives only a bit faster than standard and the turbo sound quietens down.
when you turn the ignition off and on straight away the extra boost comes back.i had it re tested by the remapped and could not find any faults but said diverter valves are prone to going wrong so recommended i changed that.
i replaced it with another but its not an uprated one so did little or nothing.ive changed air filter into a performance on,coli packs spark plugs but still does the not so fast mode.i have no warning lights.is there a different type of diverter valve i should be using and if so what model number please.the remapped told me from 150bhp has been increased to 30 or 40 more bhp
