Good news! Had a slight downpipe leak sorted, whacked a gasket in. Just been on a spirited drive and it boosts nicely! Swear it's quicker than before. Glad to be back on the road at full performance :). Considering a remap though to make sure it's running in sync.
It's cold here but no sign of snow, right on the coast though so probably wont get any :(. There is snow in the hills though, might venture out tomorrow night and test out the awd system :P
