So what I have is my 04 cobra with a 4# lower and 2.2kb, 80# injectors probably pushing 18-20lbs of boost and all supporting mods. What I'd like to do is get the proper fuel setup to run gas and e85. What would ya'll recommend for the fuel system? What about the Lethal performance budget return style system would that support both gas and e85? Also with a return system is it necessary to run BAP, and dual fuel pump driver modules? If anyone can help it would be greatly appreciated thanks.
