I only had stage 1 for a week before I upgraded - but yes, there was a noticeable difference. Stage 2 map 1 is pretty much dailed in from what I understand, map 2 refinement is next for this tune. In think this will be a great step forward in getting these cars to show real potential. Once we have FMIC options things will get really exciting. For a tune meant for a completely stock motor stage 2 is definitely an improvement.
