yea i have a 2 step and never use it. it just basically allows u to launch ur car at a certain rpm at full throttle bc as long as the speedo reads 0, that particular rev limit will engauge. u only really need it at the track. otherwise ull have to have 2 different 2 steps for the street and track (bc ull hook different at the track).

n +1 on the ectune. much better than crome from what i hear.
