21st Apr 08 Hi Andrew, Box arrived on time on Saturday about 11am and eventually I manged to find the plug at the end of the fuel rail … a little tricky to spot and get to but no more than 15mins to fit and cable tie round the engine bay …. What a difference it makes though, have done about 150 miles since !!! I am now convinced it goes as well if not better than my previous Fabia vRS …. the lag below 2k is virtually gone, I’d probably say 90% better when slowing down approaching a road junction and it pulls like a train in the mid range now …. 3rd gear particularly pushes you back in your seat under hard acceleration …no sign of any smoke either .. am running on BP ultimate to give it that little extra too !! Many thanks for your advice and help with buying the box and the great service to date … Regards, Simon
