[Shotimes] How to get 300HP from your 3.0L SHO engine

[cmichaelo@optonline.net]

Well, I think the main reason why noone has seen 300HP yet is two-fold...

1) their fuel injectors probably can not keep up (so in reality, I should have added that to the list below), and
2) the wideband HEGO and tweecer are really needed to increase WOT hp (bascically, noone has this mod yet, as far as I know)
