I purchased my power pup and am very upset for doing it. The box it's in says it's upgradeable online, and is up to 230 hp. This is not true. I purchased it, and when I contacted BullyDog for the upgrade to crazy larry I was very let down. My box is for a 2005 model, so it's not very old. They told me that was their older style programmer, and to have the crazy larry, I would have to purchase the triple dog downloader. It just kinda sucks since I bought this box for that program, and now they won't honor what's on the box the programmer came in. I guess I should add a positive note to all this. The 130 hp program makes nice power. I want 13's, so the 130 just won't cut it.
