Am I better off fitting a turbo or DieselGas Sequential II?
For performance, both. This system delivers real dollar savings at the bowser, as well as extended range and reduced engine wear (and will not increase emissions). While producing extra power in its own right, the system will also significantly improve the gains of any other performance modification. Dyno testing has shown the system will still deliver up to 20% more power on top of any other performance gain.
