I was wondering if anyone is running a similar set-up. I am about to spend the money and wanted to see if there are any better options to go with. My truck has about 90k mi and I am ready to get a bit more power! I have an 04, 3500 dually, 4x4, it is a 6 speed with 4. 11's. BUt, I am running 22. 5 alcoas on it. I do a good bit of towing(about 25-35k a year towing about 10k lbs. ). So,it as to have good spool-up. I was thinking about running a HTBG or HTB2 with a good adjustable box (Edge or TST) and maby some mid size injectors. I know I am also going to have to do something with the fuel system. I was thinking a FASS would take care of that. I am also going to need a good clutch. Not really shure what to do for that? What would be good for a set-up like this? I was also thinking about a cam. Are these worth the time and money?
