any suggestions for a cost reasonable way to go faster? lol i am really looking for 1/4 mile improvements if that helps any
What other mods do you have? Will an LS6 get you 1 or 2 tenths...sure. Will other mods (depending on what you currently have) get you more...definitely. And the ported tb isn't going to make you faster or get better times. Just a little better throttle response.
