Hi Mike. My mods are in the link on the first post. It has a tune revision from Ken and it has been on a 3.0 pulley for about a month and a half now. 16.4psi was the max boost seen at redline on that dyno pull. Thanks.
6 rib setup still? What size pulley was the lower dyno curve?
Bone stock headers and stock cats. I just wanted to show that they are not a huge restriction as most claim as long as you're not abusive and overheating them and have a good tune. Just like @isthatahemi, I like a mild sounding truck and headers and catless are a bit too much for a street driver. 6 rib...yes. I have seen it peak at 17.0-17.2 on the street sometimes but normally it's in the mid to high 16s.
The second pull on the first graph was exactly the same as the first...just dyno guy not doing stuff correctly. He was not opening the throttle correctly. He didn't go WOT until 5K on that one. He did it a little on that first pull too that's why the plot looks kinda weird down low.

Thank you bro. Truck is a beast. I knew it was making power when I can't go WOT even rolling at 25mph in 4x4....lol.
