That car had been mapped very badly within an inch of its life so not the greatest example...
Putting £60 of cheap stuff in or £10 is not going to make any difference in the long run, I would ditch the V Power and use Tesco Momentum or Sainsbury's super, both cheaper and the correct Ron
yeah it was mapped on v-power and then run on normal i'm sure though
From what Keyser said I think it was mapped for rocket fuel and run on moonshine
I still have the map on my ecu log I'm sure
Ah yes you bought the Haltech didn't you....
