I have an 03 4x4 ctd, with the Bullydog Triple DOg. I was looking for more mileage from a module. HAs anyone tried this ROI module? I was planning on trying stacking the BDTD with a module and trying just the module alone to combat the 2. 60-2. 70 gallon fuel prices. I am only getting about 17 mpg at 70 if I am lucky, and am furious. I have Dick Cepek fc 2's 35 12. 50 17's and 3:73's, auto, and just installed a Banks Monster exhaust(single), very nice part btw. Also, removed my silencer ring yesterday, does it hurt mileage or power to remove it? It sounds cool!
