I've been reading through different "Tune" threads and haven't found these two compared. I'm curious if anyone has any insight or experience with both of these tunes and how they compare. I would be going with Alpha-N on either. The RK tune is significantly less but I wanted to know if it's worth putting down the extra cash towards the Evolve tune. My car is stock (muffler delete, so still stock). Sorry in advance to light off another Tune thread.
