i dunno really how much horsepower these make... maybe after i drive it some more i'll have more of an opinion.

I will say this though, i spun the truck out on the test drive. Before, i could barely turn my 30" tall bfg's... now i'm burning it into second gear. (ooops, happened to be going around a corner) i ended up facing traffic on a one way road..... and looky here.... mr. popo is two cars back. He didn't even stop me.... i wonder if he's lazy, or just felt i'd been embarassed enough.

Motor definatly like to rev up now... but i don't really feel it too too much on acceleration..... but from a dead stop, flat foot it's great now. before it lagged. also, my cruising speed (if i'm doing the speed limit of 65) before felt a little weak, so i'd have to at least do 75 ( like everyone else). Now, if i want to obey ( no!!) it'll cruise fine.

overall..... worth the used price of 165 shipped.

 

Glad you liked them. I noticed a nice gain from them when they were installed on both of my Sierras. Now get that idle up to about 600 rpm's and you should see no significant voltage drop.

 

it already idles around there,superchips do that?
