what software do you have david? mine is also 100 cell cat and i got the light but it was nothing to worry about, although not knowing what was wrong at the time i drove off boost and very slowly for a few days! by the time dom told me to open it up to log it i completely forgot how quick it was! nearly cacked my pant going sideways toward a lorry!
the reason i got the light could be down to a number of factos though as my system was fitted incorrectly but speaking to carl at revo if i get the light again they will have a look at the code for me.
