    Supercharging

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    huh. I guess I just expected it to read current at all times. mine being overly complicated BS shows the current of everything all the time haha. oh well, external clamp it is.

    08 denali awd wont move, diff fluid on the driveway

    not really sure how to explain it. but in a rwd car with a open diff, if you spin one tire one way, the other side spins backward when it park. to technically if you lifted one tire off the ground, even in park you could roll the truck away. the awd has that same rear diff but also a center...

    I would think you could read the amp from a tech 2?

    Supercharging

    ahh 91 you must be up high, I've only read about the thin air issues. how's the vortec do for intake Temps up there at 9 lbs. grew up in the sea level life where 8lbs of a s trim didn't even need an intercooler. on a side note, I get that boost is restriction to flow, but say you took the...

    that does sound like a lot. if I had to guess you had that 160 maxed out. I have seen right at 100amp in my car testing it and it doesn't have anything like that much to turn on. I'd love to know what the ecm was saying the amp draw was at that time. sounds like you got a good one on there and...

    I totally get bringing a spare in long trips, especially if you have one that works. usually electrical stuff lasts longer the less it's pushed to its max ratings. especially with your camper the 220amp alt would seem to he a logical swap

    Supercharging

    wow I'm surprised it had heat issues at 6 psi. but I guess the 6.2 needs 93 fuel stock, I wouldn't take much to rattle one. interesting. I could see warning lower compression.

    the step is they put it on a test stand, spin it up and see if it charges. since he doesn't wait till it breaks, they won't replace it on a time basis. they only replace broken ones. these days on most cars/trucks the alternator is considered a life of the car unit. I remember when they failed...

    Yet another Yukon with engine tick and low oil pressure

    it's the craziest thing.. it doesn't sound like valve train to me either, but I've never heard anything knock like that when cold and go away. any time I've been around bottom end stuff, like main or rod bearings they all get much worse than hot.. can almost sound OK when still cold on thick...

    14 LTZ Shutter/shake/ vibration under light throttle

    might be a good idea to get the 4 cyl mode turned off as soon as you can. I doesn't keep it from eating lifters but as far as I've seen, it doesn't hurt and you'll need it turned off anyways when you go full delete

    upgrade to the newer 220amp unit. you can get them off low mileage take offs on ebay for under 200$ and a direct bolt on unless you wanna be a bit extra. all the numbers to look for arw on iamdub built thread.
