S1 rallye box's

  1. #1
    Hey recently purchased a s2 rallye. Was speaking to a friend with an s1 box in his VTS and he said he was gettign 4000 rpm at 70 and my rallye is equalling exactly the same? anyone shed light into maybe why this may happen or do i have an s1 box without knowing it? Cheers
