    Black Bear Chicago Tune

    Chipping in here. I also have an 07 burb tuned(not blackbear) i didn't realize i had 3.73. Couldn't figure out why my mpg was so bad, gears don't help. I get 14-15 cruising flat at 70-75. Sent from my SAMSUNG-SM-G891A using Tapatalk

    Fosscore's 2013 Suburban LTZ Build Thread

    Mine is supposed to arrive tomorrow. Can't wait. Planned on keeping the suburban stock. Now I'm at tint, exhaust, lift, tune, about add drop in and intake tube. Some sweet burbs rolling around! Sent from my SAMSUNG-SM-G891A using Tapatalk

    Hypertech max energy. Disabled AFM, increase shift pressure, 87 performance tune. Scored a really good deal on it. Wasn't looking to build a race truck. Just wanted to disable AFM. Other settings were a bonus. Sent from my SAMSUNG-SM-G891A using Tapatalk

    Wow. Tune is cool. Don't think there's any noticeable added power, but throttle response, shift firmness, and mpg are improved. Sent from my SAMSUNG-SM-G891A using Tapatalk

    Installed tune tonight, disabled AFM, performance, increase shift firmness, and top speed. Even though i haven't had a vehicle over 80-82 in years. Maybe I'll hit 140 one day! Sent from my SAMSUNG-SM-G891A using Tapatalk

    33s, Gears, and MPG

    Hey guys. Bumping this. Would like some more input on sizes. I installed 2.5/1.5 lift Saturday. Really like 305/55/20 but worried about mpg taking a huge hit. Anybody on 285/65/20, 275/65/20? Thinking tall and narrow may not ding the mpg so bad. Sent from my SAMSUNG-SM-G891A using Tapatalk

    Knocked out some stuff yesterday. Did the top engine cleaner, changed spark plugs, installed lift, switch to synthetic oil. Spark plugs 1 and 6 were bad. Mpg went way up on the drive home. 17-18 at 80mph. Have a tuner on the way, going to disable afm. Hopefully this fixes me up. If not...

    Update. We finally ran the scanner. No codes or misfires. Mechanics guesses were valve cover pcv, or something else where we would have to drop oil pan to get too. However. It is burning about 1.5qts every 200miles. That is insane too me. Going to try and run the top engine cleaner and change...

    Yeah, i really don't want to go through selling and buying. We'll see. Two a days and start of school is not the time to deal with this crap. One of my players dads looked at it this afternoon. He is a chevy mechanic. He's going to take to the dealership tomorrow and run diagnostics. He said...

    Thanks. Yeah, really don't want to buy another. I HATE spending money. I'm going to try the things you posted and see what it does. Then I'll figure it out. Sent from my SAMSUNG-SM-G891A using Tapatalk

    125k miles. I'm mechanically inclined. But not enough, nor do i have the tools to do a job like that. I thought everything I'd read was after 09 they fixed the issue. Other bonus would be six speed. Literally settled for this truck because of price and how clean interior and maintenance...

    Any input on why mpg would drop? Or the big white cloud on start up? All from the same? I am just concerned about lifters already failed or about to, valves, etc. I don't want to throw 4k in repairs at a 10k truck. Sent from my SAMSUNG-SM-G891A using Tapatalk

    Can i expect any of that to actually work? I'm just paranoid about it, usually whatever the worse case scenario is happens for me. Strongly considering selling it and buying an 09-10. Sent from my SAMSUNG-SM-G891A using Tapatalk
