    Is this the fix for 2016's? Mine is doing it pretty bad. Well bad enough it is bothering the crap out of me. Is your seat still good?

    Wait. You soldered a diode on to a $600 board just to have fogs when your high beams are on? I have never heard of this mod and judging by your experience i do not intend to perform. Light output is just fine for my wallet. lol. Thanks for posting this warning to those of us who had not heard of this. A really nice LED bar behind the grill for that money!

    My 2016 does it to albeit not as bad. GM installed stops next to the white plastic rotating pieces but there is still a small gap. I will be installing a zip tie to make up the difference. The zip tie will be a wearable part so it may be replaced from time to time.

    Anybody put the MIT on a 2016 with the high capacity air box RPO K47? Airaid emailed me and said they cannot recommend it for my 2016 AT as it has not been tested

    i just threw in some 89 to see if it makes a big enough difference. I will log some data and compare the 89 and the 87. I need 10% better MPG for the boss to justify the 10% increase in cost per liter.

    Correct me if i am wrong guys but isn't the check valve for boosted applications when there is a possibility of positive pressure in the intake? NA engines don't create positive pressure in the intake unless an intake valve is stuck.

    Afm lifters are still garbage apparently. Tuned mine out

    93 in a 6.2 i understand but why in a 5.3? unless it is tuned to run on it. A stock 5.3 requires no more than 89 (87 mfr recommended) at best so why the added expense of higher octane? Here 91 is roughly 50 cents more a gallon.

    Although I don't disagree with your logic, in fact I agree with it, when the boss is willing to pay up to $200 a week for gas I will have go that route. That's a mortgage payment every month. So I guess I will have to take the lower power output. That is really the only reason I run 87 vs 89. If I can prove 89 will save him money he may go for it

    I run tier 1 87 in mine as is recommended by GM in the owners manual. 6.2's are 91 minimum. 87 is all the company will pay for so that is what i run since i am 700 miles a week. I was looking at data and did not notice any knock retard being used during any acceleration. I assume this is because BBP never adjusted my timing off of the GM setting. Justin recommended 89 as it may be more fuel efficient. The compression is allowed to be this high as fuel doesn't enter until just before the plug fires. on my 64, it was built at 10.5:1 running on 100 octane gas. i have to pull timing and run 91 shell or 93 other to prevent detonation. With the fuel entering just as the spark plug fires, aluminum heads and block, 11:1 is achievable on 87

    No drip oil applied with a long piece of tubing. My 08 was mint and I did it every October

    The GM Borla for the 2015/16 come in two sounds i believe as my coworker's is louder than mine but his is on a 2013 so no flapper. It's loud enough for me. I don't need to hear inside the truck with the windows up

    To answer my own question, TM is required in the transmission as part of the design of the transmission (clutch to clutch) not so much to extend the life of the clutches but for the hard parts usually the output shaft or the drum. It looks like the 6l80 can handle the input torque of a stock 5.3 even a slightly beefed one. (CAI, Exhaust, tune) may run into issues with a turbo or SC if you drive it hard. Maximum engine input torque for the 6L80 is 440 ft. lbs. and the maximum output torque is 664 ft. lbs. The case is die cast aluminum. So, i suppose some TM is required in the transmission but, can be removed from the engine.

    Please explain how a little bit of slip is better for clutches than none? Any time a clutch slips it wears and creates heat. Smooth shifts are slipping clutches.

    Isn't it deactivated in anything but M6? Anyway, I thought maybe it could be a vibration from the backpressure (flapper) valve. Not a huge deal to me as i am rarely going that fast. i just wanted to share my experience.
  17. Willshire
    M5 mode? I didn't know it was a mode lol. I thought "manual" was the mode. whether it's M1,2,3,4,5. Anyway, i put it in manual and downshifted to 4th at 90MPH to see if high rpm was the cause. It was not. I agree there is a possibility my Borla is causing it under WOT as it does make a lot of sense if i am deep in the throttle. Wind doesn't make as much sense because as i said, only under WOT. Couple the two together and maybe we have something. i don't spend much time up at those speeds as the limit is 50MPH or 60 on the 4 lane 401. so i might see 80 max. I was passing when i noticed it so as you can imagine it wasn't for long. Other than that truck has been awesome. Glad you got sorted out mike
  18. Willshire
    I tried to replicate it in M4 thinking high rpm but it only did it in WOT. Ring and pinion mesh under high twisting force at high speed maybe?

    Anybody have a link to a discussion regarding a vibration under hard acceleration above 80MPH. seems to stop when i let off the gas. i searched using vibration hard acceleration and got nthing thanks

    If air has to be exchanged in the cabin, doesn't the smell of the air come in too? Charcoal filters take care of smells. I don't run recirc during the winter as it fogs up the windows. i'm sure there is science as to why so i leave it in fresh air. Under max a/c conditions in recirc all i smell is the a/c. If unwanted smells are the worst of your problems in life, i sure would like to trade spots with you. I live in the country, if i don't smell cow crap i think there is something wrong LOL.

    This is the wildest thing. That Vibration absorber has been used by GM before! Long ago. 52 years ago in fact! In my 64 pontiac, it came with a 3 speed automatic called the "rotohydramatic" TH350 came out in 65. The "Slim jim" as it was called, had an internal torque converter, called a torus. Where the torque converter should be, they had a damper plate, essentially the same thing as the Vibration absorber! http://sandyblogs.com/techlink/wp-content/uploads/2015/11/F08-trans-3-pendulum.png https://www.google.ca/search?q=pontiac+slim+jim+damper+plate&rlz=1C1VFKB_enCA653CA653&tbm=isch&imgil=UTHp9THOt9k_0M%253A%253BnhchbDRBPnC0SM%253Bhttp%25253A%25252F%25252Fwww.autotran.us%25252Fdamper_plate.html&source=iu&pf=m&fir=UTHp9THOt9k_0M%253A%252CnhchbDRBPnC0SM%252C_&usg=__bmCdovgGraGzt7sIzq05BEE78mE%3D As you can see they are the same idea. Now, the slim jim was a total turd but, just goes to show old tech has new uses. LOL

    Anything that is not fuel or air will make the truck stumble, if you sucked a big gulp of the stuff in, sure it would almost stall but i don't think, at the velocity it's being pulled in, much would get stuck on the valves. Puff of blue smoke or white smoke (steam) and if it was real bad an engine code. empty the can, start it up, may run rough for a couple seconds but it would be back in business. Remember, you aren't hitting the back of the valves with tiny droplets, you actually wash the back of the valve with water/oil but, i suspect the water would be the predominant liquid. At least this time of year in the colder climate

    Silly me i thought the stops were in the rack and the stops to the control arms were secondary stops. A lot of four wheel driving may cause that because that's a lot of full steering on 9k miles.(unless it occured while you had it after the lift) So, after reading the Ackermann tech sheet, i suspect when you modified the lift, (forget how much you lifted), you changed the angle of the tie rods from the rack. Essentially your tie rods went from horizontal to 30+ degrees angled down. Now, after you set the toe, castor and camber back to original specs, does the travel of the tie rod change since the angle of the tie rod changed? I would guess after they set the toe to spec, (likely some outward turns on the tierods to make up length) the turning radius of the inside tire increased and the outside tire decreased screwing up the Ackermann angle from the increased angle of the tie rods. If the rack was moved with the lift then all of the above is moot. lol

    Only at full steering lock in either direction? I had factory size tires on my 08 and it did it. i thought it was normal. You can't, at least i don't think you can, align a truck to go straight down the road and to make turns at full wheel lock as the tires are turned to the same degree right? Let's say it's 45* on both tires, the outside tire needs less than 45 degrees to make the same turn with the same friction. Again, i thought screech from the outside tire was normal for thie reason i just mentioned. But i am not sure, mechanics is a hobby, electricity is my job LOL

    Is it rattle your teeth or make it hard to see shake? Or is it a mild "tire out of balance" type shake? Mine has a very slight vibration but it is currently caked in snow so i chock it up to that for now
