EFI information
I think either could work for you. I had the FiTech on my slant, put 1000's of miles on it with Zero issues ( other than a handheld connector issue - they replaced it ). A lot of the issues with either system, are install induced. make sure you have good clean fuel ( correct filters ) good power connections and Solid grounds. my car is now getting MS3 ( i wanted multiport ). you may want to consider an in tank pump as most wont live outside and are Very noisy out of the tank.
