There isn't much extra left in it to try and extract with cheap mods. The V is the way to go if the stock Northstar isn't enough. I love the V8, but in all honesty, I don't think I use all the horses on a daily basisAhh alright thanks guys and yeah I know I can do all I want but its still an 05 STS maybe time for an upgrade and if im looking for speed I should give up and just get a V
