I think Derek Robinson effectively went from TSP Stage 2 to W1 and reported earlier in this thread. Of the second part of your question I have no clue.I think someone asked this already, but how noticeable of a power boost is going from a tsp stage 2 to a w1 drop in? If I wanted to keep my downpipe stock, ( don’t want much louder already have greddy catback), would i be losing out on a good amount of power ?
