Did u check out the FAQ's?? That's such a common question asked, they went ahead and made a page with free mods, commonly used abbreviations, basic engine specs...the works. Jus click FAQ in the tab bar located top center page under the LS1LT1.com banner
There's a throttle body bypass, air silencer delete, cat remeoval (dont do that)
Mass air flow screen removal (dont do that either lol )
I think there is onr more but i cant remember it.
The throttle body bypass will prob give u 2-4 horses if even, its an easy simple mod that will take maybe 40 minutes.
I would just do the throttle body bypass free mod wise.
