Big Stuff 3 EFI Systems

 
 

Note: Many different systems and options are available, please be sure to scroll down to see all listed items

 

Developed by John "Bigstuff" Meaney, the Bigstuff3 Gen3 PRO SEFI systems provide cutting edge technology to racers and street rodders thanks to the integration of many powertrain control functions (transmission control, COP ignition control, external parameter datalogging, etc..) into a single ECU (while functionally comparable systems require multiple units). The Gen3 Pro SEFI base systems include items shown above (ECU w/ preinstalled vibration isolators, Wideband O2 sensor, software, comm cable, injector harness and main harness).

All EFI systems purchased from efisupply.com include a ECU calibration matched to your application. We have developed a large library of naturally aspirated and power adder calibrations and are likely to have the file you need. If we don't already have it, we'll work with you to develop a new calibration for your combination.

We work hard to provide competitive pricing on our entire offering of aftermarket electronic fuel injection systems and components, if you find anything we sell somewhere else for less contact our sales staff at sales@efisupply.com and we'll do our best to match or beat their price!
