GP Fuel controller
Corrects your air to fuel ratio after adding exhaust or other modifications.
These are the simplest fuel tuning devices available for adjustability on the fly.
I have custom fuel table adjustments and shift points flashed into each one. NOT YOUR BASIC "BLINKY BOX". Unlimited fuel perameters.
Each controller comes pre-setup for your application so call today and get yours for your setup..
Please tell us year, model, engine size, and modifications here before you order.
