Tuning your set-up has become even EZer thanks to FAST EZ-EFI 2.0 kits. These revolutionary self-tuners don't require a laptop or tuning experience. Simply hook them up, answer the basic Wizard setup questions, and the systems truly tune themselves--"EZ", right? Some kits include the innovative FAST 2.0 throttle body but FAST offers several choices, each a little different component wise--base kits, master kits with fuel systems, multi-port, and retro-fit kits--to fit your application with the simplest self-tuning engine control available. But no matter which one of the kits you choose you'll get a full-color touchscreen hand-held, a wide-band oxygen sensor, and a fully mesh wrapped wiring harness. Improved performance just doesn't get any EZer than this--FAST EZ-EFI 2.0 kits.
