okay guys i have a 99 gmc sierra with the 5.3. i already have a specter air intake and true dual exhaust from cats back. im just wondering what other bolt on you guys would recommend for gaining power. i would also like to know what brands of the bolt on yall would suggest.

How fast do you wanna go and how much of a budget???

you could do headers and a converter next..

First and foremost get a TUNE!! Plenty of good ones on this site. My preference Wheatley hands down. Next long tubes(pacesetter is a decent affordable set), ditch the converters, gears(3.73 or 4.11 if your truck doesn't already have one of them from factory), stall converter makes a huge difference(circle d makes a bad azz one),maybe underdrive pulleys. But tune is gonna be a good place to start bud.

The list is endless... Have you done some browsing and searching on the forum?

thank you guys. yes i have done research on here, but every forum has different advise so i was just going to ask again and see what answers i got.

i dont really have a price range just because right now i am just looking into what i could do and what could be done to this truck.

i do know eventually i would like to upgrade my cam and heads, but right now i am just looking for simple bolt ons that wont take lot of work to put on and just give me alittle more power.

another vote for headers and tune. id wait on the gears for now since ur 4wd and hold off on a tourque converter until you figure out what your goals are and what h/c setup you would like. some long tube headers and a custom tune form a sponsor would be your best bet imo
