if your in good with a dealer, they can put trim codes in, ive not heard of 6999, but i know theres many that work. they can also change your fls fts numbers if they know the special numbers and know how to wash an ecm, for free. having a rerate done is like 400 to 450 i do believe. fuel temp and inlet air temp sensors work well too. be very careful with bullydog or pittsburgh power, they can do a lot of damgage real fast if you dont watch what your doin. we had one melt down on our dyno one day cuz they were playing with their bullydog on it
