Optimax or Tornado?

The Optimax chip
The Optimax Chip has been designed for all standard and mild tuning on the 3.9 Morgan only. It will add substantially increased economy, throttle response will become far more crisp & responsive, idle will be smoother with enhanced pulling power to your vehicle, and in most cases is the ideal upgrade.

The Tornado Chip
Essentially the same fuel profiles as the Optimax with more top end and revised fuelling for the bigger capacity engines such as 4.6 and beyond (without loosing sight of efficiency). Whichever one you choose, you are going to be pleasantly surprised by the huge gains achieved by such a quick and simple upgrade. This following information will demonstrate just how simple the process is.
