DiabloSport Performance Chips

While the tuner took an hour or so to get connected to the internet to update, the process of applying the tune to my car was painless. I'm running the 87-tune, and I can DEFINITELY see an improvement in performance. Throttle response is nearly instant, and has noticeably more low-end power from the tune, even on the lowest octane tune. I highly recommend for one of your first mods.
