:-{} Which do you think is better a down loader or a superchip. do you think a Bully dog monitor and a Quadzilla plugin module are better than just a down loader. The only advantage to a guy like me who only wants a little more power while pulling my trailer is that the Bully dog with the superchip will allow you to shift on the fly. :--) I will probably never use the 100 horse increase! What do you think. I was thinking that a downloader might be better to keep from anyone knowing that I have modified the truck. I have found a great deal on a Bullydog monitor and a Quadzlla supermodule. But I have also found some great deals on Bullydog pup ( downloader) I even found a good deal on a edge ez module? Which do you think is better and why? I am leading towards the Quadzilla and the Bullydog module as it is a great deal. But have many questions.
