The Dynatek system is a self tuning/learning system from what they claim. Not sure how that is accomplished without a mass air meter. The TWM is a speed density system that will need an experienced tuner which when it is all said and done may cost as much or more than a self tuning system. You might want ti look into a Massflo system with stack injection. They don't offer it but I heard they will work with you on special projects.
