turbos might require tuning.. but alot of tuning from superchargers also require tuning anyway.. so i dont think thats really a major concern.. i got a base tune from SCT and it works pretty well.. might not be for optimal power, or fuel etc.. but it works.. i can't imagine how the supercharger companies "have it easy" compared to turbo and have better tunes.. all cars are different and even identical cars will probably need different tunes to run perfectly..
