well i have an 06 cummins and i am trying to find out what setup i can do thats still very reliable and worry free. So far i have a intake 4in MBRP exhaust and a BDDL.....i was thinking of VB TC and then get rid of the BDDL for a TST and new lift pump and maybe CP3 mod. Is the TST a good box for me or should i do a smarty? i want to be able to control fuel milege and adjust on the fly because i run the BD on extreme all the time and people are telling me its killing my fuel but i havent got a chance to check it so im not sure. Would this make decent power? or should i look maybe into an edge or something else?
