No worries mate
I'm running a HKS Vpro Gold V3.2 ECU, there is no spool at all or any turbo relative noises, it drives like a totally healthy na supra its like its just forgot it has a turbo lol, nah there are no boost pipes or anythin off, admittedly I'm no mechanic but all the turbo setup seems fine to me (apart from the fact it's not working obviously lol) which is why I'm thinking its a failsafe on the aquarist system. The tank of water/meth mix did run out when it happened as the low level light in the dash didn't come on by I have since filled it up and still have nothing, the water/meth mix is being pumped around as I can see it moving in the pipes under the bonnet whilst revving it
