We had a Customer S3 in Saturday for mapping his S3 with BBT K04 hybrid on. It made some great numbers... 345bhp/303(352)lbft Dans BBT k04 hybrid, relentless v3 (ported by owner), rods, wmi, 3" downpipe, 80mm TIP, 550cc injectors, Welly cooler. Very well presented car. Leak free ! Lower plot is the lowest map 5 boost setting.. 5 x boost maps.. Anti Lag boost build launch, no lift shift etc.. Rapid S3 up in Chesterfield. Watch out..
