I am running the bully dog power pup in my 2004 lb7, and in any mode I will put the pedal to the floor and it won't get up and go until it get's to about 3,000 rpm's. It's like it has to build up for like 4-5 seconds and then respond. I also have an AFE stage 2 cai. Is this something i just haven't noticed til now or do I have something wrong???
I t is most likely just the tuner. Bullydog doesnt have a very good reputation with the Duramax. If it were me, I would sell it and get something else like PPE or Edge CS/CTS.
