I just got a brand new 06 v6 auto and have a few questions since there isnt realy anyways to search this site. 1. Whats the best intake without reflashing the computer 2. Is it realy worth changing the underdrive pully? I know u get some hp how of it, but is there anything bad about changing it? 3. whats some other engine mods that dont cost to much that i should do? im kinda new to the v6. i used to have a crapy civic.
