Solid tune is good for about 20, CAI just get an ebay unit for less than $100 maybe 7 or 8, maybe, headers and a decent exhaust (NOT Flowmaster) maybe 30ish

For your last question

Well that sounds good, and I love the way my truck sounds but its just too damn loud, and its all factory exhaust except for the mufflers, it has way too much of the "droning" sound, especially when towing. I pulled a truck yesterday and it annoyed the hell out of me, but if I get longtubes and remove the cats, or get some high flow cats, ill get some kind of different mufflers also. Do I have to remove my computer and send it to Nelson or do they send me one and then I send mine back as a core? I don't want to have to take my computer out for a week and wait on it to get back because my truck is my only vehicle right now

You fill out the tune form, he ships you a tuned ECU, you ship yours back to him. Easy and no downtime. I think the main question is how much do you want to spend. Good cam kit, LT's, cheap intake and tune will run you in the area of $1400-1500.
