I own a 99 chevy silverado 1500 with a 5.3L. I'w wanting to do some mod's to it and was wanting some input, if there are any free mods out there please let me know.

thanks

 

Well you can do the tb bypass, egr mod and tb backstop grind for starters. Then there's the home made ram air for the adventurous. Your best results will come from a programmer, I use superchips, a free flowing intake and exhaust. Exhaust is a matter of preference as there are so many choices and sounds to go with. There are instructions for the free mods at ls1.com and installuniversity.com <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

thanks for the input, i dont know much about mods really, just that every little bit helps, and i want a nice ride that will last, thanks again

 

check out the spot he told you about the mods are not that hard I've done them all except the egr trim just havent had time, but the tb bypass and grind on the bumpstop where both done in an hour. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />
