Stumpy, none of that sh1t works, I thought you knew that? What is that like 3 grand for all of it? Will it amount to 15hp? The hot-air kit will just take it away and fill your motor with dirt for good measure.
The 5.7 from the Factory is as perfectly tuned as it comes. In '03 when Hot Rod went through the new engine with a fine-tooth comb it was pointed out the factory manifolds flow within 2% of a set of headers.
If you really must have headers, 6.1 factory headers come up all the time on Craigs List from some Meathead duped by some header advertising. Usually $100 can get them and they won't leak like that aftermarket crap.
The rest of your laundry list, well pick one at a time and just Google "Problems with ___________" and see what comes up, I don't have time waste on it, seen enough of it already.
Wow, what a bitter person.
Headers don't make power.....Crikey, How many times do we have to hear people tell this lie?
The cold air kits do work IF they draw air from outside the engine bay. I have 282,000 miles on a 2007 Ram that has had a FRAM kit. It runs clean and is still strong. The filter is an oiled K & N that I also hear people complain about but the engine keeps on running.
I do agree though that some of the electronic tuning is not cost effective. The amount of money spent to gain 11 HP to the tire is steep. The traditional methods still work though: Less restriction of the incoming air and of the outgoing exhaust.
