Been a while so let me give you the scoop on things. We installed some parts and did some dyno runs as we went.
AirAid on factory truck gained 20HP over factory filter
AirAid w/ electronics gained 25HP over factory filter
Smarty w/ Edge CTS definately gave a HP gain but I can't remember the numbers. Somewhere around 100-120 HP. I daily drive it on 3. Ran it up to 9 for chits and giggles and it seemed to get quite a big more lag to it. So I put it back down. 3 and 5 work great though.
H&S had some problems. I think how I downloaded it more than likely. Because the bone stock truck made 65 MORE HP than it made with the H&S plugged in. Even with it turned all the way up it made 35 HP more. So I definately have something wrong with my H&S. Again, more than likely I am the issue LOL.
Yukon 4.56 gears went in along with the mag dif and trans covers. Gears were a HUGE help. With the gears and exhaust delete the truck gained 7 MPG. Went from 9 to 16. So I'm definately pleased.
Now I'm waiting for Steed Speed to finish up the new manifolds for these trucks. When they do it will go on with the billet 63mm wheel from Fleece and ARP studs. More than likely the Suncoast will be going in at that time. The stock trans seems to be doing just fine right now. Took a little bit for it to learn the new power. Once it did it seems to shift fine. I'll see about getting the H&S fixed up with results.
