    The Speeduino has been great since day 1! Base tune makes a big difference and my little 1.6 actually pulls now. Customer service has been great and the guys at Speedy EFI have been helping me at every wall I hit.

    Megasquirt looks fancier but who cares when it’s under a floorboard. I have had both. Customer service/tech support is worth 50 stars. I will solely deal with speedy EFI for ANY fuel management on any vehicle from here on out.

    This is a company worthy of giving your hard earned dollars to.

    Solid construction of unit with tight pins and outstanding customer service.
