hey guys. i just bought a six psi roots type supercharger that came off of a joe gibbs truck. i have no idea what kind of fuel management those trucks have on them stock. im wanting to do efi live on it but i dont have enuf know how as this is my first supercharger, my main concern is that efi live retunes the stock map so.......... will the truck even run on the stock map with the charger on? do i need to run it that way before i pull the map off and email it to the tuner? do i need to buy a wide band o2 sensor first? is there a better/easyer/cheaper way of doing it? better to just take it to a dyno? i know efi live is the best thing out there and im willing to spend the money on it if it is i just have no idea where to start. any help would be greatly appreciated. thanks!
