    Shorty Headers on 2013 6.2L - yea or nay?

    Tough call. My Denali has low miles (88k) so investing now makes sense. Funds are low, however. I'd be content with a very modest performance increase, so long as it can still work with the setup you recommend. Does it make sense to save this all for when I'm flush again? Or go for the exhaust...

    Engine stumbles at startup, stability and traction control warnings - Causes? Safe to drive?

    Like you all said: electrical problems. Rodents ate my wires.

    Black Bear has earned by repeat business either way. Great guys.

    Shorty Headers on 2013 6.2L - yea or nay?

    Update: stock manifold has begun leaking. If I'm going to spend the $$$ to fix it, I'm attracted to the idea of long tube headers. I got the BB tune earlier. Buy the headers and let BBT have another go at it, im thinking. How good/bad an idea this is, and if I go for it, should I also install...

    Engine stumbles at startup, stability and traction control warnings - Causes? Safe to drive?

    If you like, I can answer each question individually. It gets regular servicing but hasn't needed repairs in the 10k miles I've owned it. No idea about the plugs and wires. I was planning to have it serviced & inspected this month anyway, so I'll definitely inquire about the above. The things...

    How hot/cool should ventilated seats feel?

    I's a 2013

    Engine stumbles at startup, stability and traction control warnings - Causes? Safe to drive?

    (1) Overnight, my 2013 6.2L with 85k miles developed a stumble/hiccup on startup. Used to fire up with the shortest turn of the crank, now it takes about 3x-5x longer before firing up, and it just sounds "unhappy" to my ear, but after this it drives normally. Hard to describe---best I can do is...

    How hot/cool should ventilated seats feel?

    Yeah I did fall off the radar for a bit, didn't I? My bad. Living in the PNW, I rarely get weather below freezing, and not much below when I do. My seats' performance disappoints me, but when it comes to addressing the issue, the juice isn't worth the squeeze. The heated steering wheel still...

    Black Bear Performance review after several months - engine, trans, AFM/DOD

    If you're talking about the stock trans, this surely is an EPA MPG thing. If you have the BBP upgrade, a tiny press on the pedal will fix it. Otherwise, stick it in "M", I guess? There's always a torque element in "torque converter".

    Affordable and effective headlight upgrade? (I know, I know ... but I couldn't find it in Search)

    Now that's what I'm talking about! Agree that the SS3 fog lights will show you the deer in Alaska even when you're driving in the lower 48.

    Affordable and effective headlight upgrade? (I know, I know ... but I couldn't find it in Search)

    That's a beautiful unit. I may go for it in chrome. Edit: Rats, they're out of stock in Chrome. I'll contact them.

    Black Bear Performance review after several months - engine, trans, AFM/DOD

    Been running my tune for a few months now (2013 Denali 6.2). Overall I'd say it's a great value and a satisfying purchase. A few points in no order. CUSTOMER SERVICE: The guys are all great. They pick up the phone right away, respond to emails, and to their credit they never once displayed any...

    Ac light blinks three times when pressed? And it seems the compressor is always engaged?

    I have a somewhat related problem. My AC button and operation work fine, but my Recirculate button (which used to work fine) does the 3-blink think without engaging the recirculation function. If it weren't cold and dark out (and if I weren't a lazy bum) I'd check the fuse, but while I'm here I...

    How hot/cool should ventilated seats feel?

    I'm not certain how well my heated and ventilated seats are working. Hot or cold, when I crank the settingto max (3/3), I can barely feel the effects. Something is working, but not a ton more than the placebo effect would be expected to. HEAT: unlike some cars I've had, the seat in my Denali...

    Affordable and effective headlight upgrade? (I know, I know ... but I couldn't find it in Search)

    Having had GREAT success with the Diode Dynamics SS3 Pro LED fog light replacements, I find the actual headlights on my 2013 Denali largely useless---factory high beams are not nearly as effective as the LED fogs. On occasion, however, the fog lights don't reach quite as far down the road as I...
