Anyone have any idea's on getting more power (h.p.)) out of a 2006 4.3 v6.
What have you guy's done?
what mods have you done? if none, start with the basics- intake, exhaust, programmer
Check with "goldie" He's got a 4.3 that's been worked over. But like he said Cai, exhaust, programmer. Lesser amounts underdrive pulleys, electric fans,cam, depends how much power and money.
