Turbochargers
efi2000 has a vehicle library of common engines and parts you can select from. Picking a part fills your project with verified data, so you can configure it quickly, and that data is used to improve your tune.
Turbo flow and spool points set realistic boost targets. efi2000 uses them in the boost target generator and to shape load bins and fueling where boost arrives.
