Re ran some of the catch can lines. Broke one check valve so tried to order one screwed that up and ordered two. Oh well. Header is installed. Should have been easy but took me a hour. I used a gm gasket and copper rvt seal. Google said factory spec is only 11ftlb. But I read after market with reused bolt is more so it got more. Odd thing was auto part dont have the donut gasket for the header to exhaust. Lucky I had one. Still need to do the maf breakout. Before next weekend. Waiting on my second 3 bar map sensor to show up. Oh and waiting on my 8lb spring. Sent from my SM-N950U using Tapatalk
You are very correct belt drive pumps. Are common on race cars. And it is to get negative pressure, that helps the piston rings and oil. On max output race engine I saw 40-60fwhp increase. Race cars dont have power brakes. We and many others tried out gm electrical emission pumps as they can be had cheap or free. And they burn up. Sent from my SM-N950U using Tapatalk
Wow I would go with intake,exhaust, and tune. Possibly a gear to compensate for the tires. That's horrible gas mileage. I have 24" lowered and a 6 speed. Even my Escalade in college had 22" heavy as hell and got 10.2 mpg. But go to black bear and order a hand held tuner. You could email or message him first and get his thoughts.

Is it flex fuel E85 gasoline? What is your MPH now. Some people report 20-24. With the 6.2l. I get 19mpg max and 12.7 min but I have very heavy foot, turbo, and custom extreme tune. Sent from my SM-N950U using Tapatalk
Interesting. I would close up the gap a hair. But pull all the plugs and check them. Take photo. What is your AFR? Trucks run way to rich stock. Header? If so what color? This head is off a supercharged 560rwhp 2014 Silverado. That's hotter then normal as all my turbo kit never was more than gold. With egt showing 800 idle 1200 max highway. My wide band is pre set for 14.7 AFR for gasoline but pump gas and my tune is 14.108. So gage is saying 14.8-15.1 at idle. So it's just a hair rich.
Batteries are shit. If you ever saw all the software for the alternator and electrical system your first question would be why, and shit battery is one main reason. If dealer fixes for free go with it. Me I did as I do in all my daily drivers went Optima and two batteries with a insulator. Why not we have two trays.
I just checked I have all channels XM and Sirus 150+ streaming All access also Navtraffic and travel link. For whatever reason my girls truck only has XM basic. HAHA don't know why it's free to us. Maybe I will upgrade and tell her it's a gift...See if I get lucky for that!
I can't remember but I do remember re gaping them lower. But I re gap all my plugs no matter what. I have gone threw 3 sets of plug wires. Turbo guy issues. First set was cheap junk the the next 2 sets are good ACdelco Race. Cheap on ebay. Only broke because I pulled them by the wire. This is why I have brand new extras. I also load the shit out of them with dielectric grease. and also titianum(cheap) plug boots. We run those even on NA cars. Way to much heat there.
