I've already went through a set of jammers, put a set of DDP injectors on the trick and love em. I also love the Aurora 4000 turbo I put on my other truck, but was planning on putting a phat shaft on my 99. The stock lift pumps are crap, changed one on my work truck about a month ago, and its already shot, now the boss is going listen to me and get a Fass for it.
