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.

 

i dont think it really matters but it is also a z71

 

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.

 

I that case I say a set of long tube headers and a tune for now then.....

 

ya i hold bolts on and a tune truck ran nice but runs better now with heads and cam lol but there right tune lts and a converter with keep u happy for a few mins

 

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

 

Another vote for longtubes and a tune
