I have the Harland Sharp ones. Simple to adjust - just torque to spec and you're done. I'd recommend them.

I've got the Scorpions. I got mine from Haulin_LS4, so you'd have to ask him where he got them from.

When I did the retinue after the install, had to add ~5% to the MAF curve. That should translate into 15hp +/-. Not really a startling change, seemed affect the top end more, so the power came on progressively through the run.

I put in new valve springs at the same time, and bumped shift points closer to 6500. Pulls to redline.

I'm quoting this, because this is pretty much what I noticed/did as well.

I can't really talk about the difference those alone made, cause I had my headers put on at the same time. With both mods done though my def pulls harder up top when cruising, and blows the tires away from a dig even more so than before.

Not too much to report; still not tuned, N20 still not complete, small issues to deal with (no remote start or cruise control). Weather has been too cold to make any video runs. If the temps move into the 40s then I will be able to post up a video.

Comp is generally considered to be the best in the LSx world.
