  1. Fuel tank size?

    Agree too small a tank for towing I have a 2017 GMC All Terrain 6.2 you would think Max Tow would have bigger tank I checkin out aftermarket
  2. Not yet they working on it be a few months more
  3. It only ads 1/2 qt ?? Or did I misunderstand not sure if that is enough to lower diff temp enpugh when towing heavy loads non stop for hours with 1500 diff i used the Mag Hytec cover it added at least 2 qts and no gasket needed has an integral o ring Instead of gasket. Dipstik and temp sensor port I was burning up pinion bearings until I added larger cap cover check my temps on long tows now never an issue
  4. I had same priblem when I had a 2004 1500 ( you should have bigger diff than 1500) I towed 12 hrs straight lots of steep grades 7000lb car trailer diff got very hot and I burned out pinion bearing twice solution was large capacity diff cover Added 50% more fluid temps went down dramatically. I added same cover on my 2010 1500 for towing. And now my 2017 with bigger diff I will check temps if meeded will do dsme not a chrome cover sheet metal cover but an alum finned cover true large capacity with dipstik Mag Hytec is brand I use
  5. Yes my 2017 came with 12v pin hot too so as said check rhe plug with a meter. The 12v hot is not heavy guage a wire so won't recharge a dead or low bat really just a maintenance charge
  6. What yr and option package are we talking about here
  7. Been on my truck k a year now 2017 6.2 at idle nice rumble at cruise same as stock no drone but when you accelerate you definitely hear it if you want noise all the time not the system but pefect for me definitely not stock under acceleration Quality is excellent way better than Magnaflow system I had on 2010 truck
  8. 2017 Sierra ALL Terrain with nav , Car play etcetc DIC trip meter I only see Trip A in the Info section of the DIC I thought for sure there was a Trip B as well ?? Did I somehow turn it off ?? manual says to go to Settings and select DIC options ........ I cant see the any DIC option in my list under Settings ?? what am doing wrong or does my truck just not have that available ?
  9. Yet if you buy the GM CAI and they install you will have no warranty issues , ironic isnt it kinda blows a hole in the “ trans cant handle the new power “. All about getting out of a claim
  10. The other way to do it is get s 2016 8 spd used TCM from a truck then it can be tuned the normal way no unlock needed by efi live or hp
  11. Changing stock D5S bulb

    OK finally installed my Morimoto DS5 5500 bulbs ......... looking for better hi beam distance , initially disappointing on high beam distance , however I was told can take up to 20 hrs of use for these bulbs to get up to full intensity ?? so I have left them on during day for past few days and yes they are brighter than first installed for me it seems they project differently than the stock bulb definitely a sharper cutoff ...... for me the hi beam is now better just took some getting used to ..... in the end the the stock projectors dont allow these bulbs to perform the best ..... they do project the road better on low beam right in front of truck no need for the fogs FWIW Im going to play around with aim setting and see if that helps on stock bulbs setting them a bit lower helped alot on hi beam
  12. Changing stock D5S bulb

    Hmmm I bot the 5500 when the deal was on too for my 2017 GMC just getting around to install them this week hopefullytonite I want to improve the high beam distance Question did you reaim them after install ?? My stock hid were terrible onhigh beam I set them down a bit made big difference even for stock bulbs on the distance they light up But of course I want better so hope I see a real improvement on high beam with the Morimotos
  13. Yes the better tires are grt idea I think you said 8600 lb trailer I can tell you I had significant wear in my rear stock tires After a 2500 mile round trip with my 7500lb trailer in high heat and high speed so The 1” diameter increase performance loss is really a matter of your expectations and or where you tow For me I noticed it for sure and I want good perf mpg was always better between 2 k and 2200 one thing you dont need a “ tune” to have the dpeedo corrected for taller tires and or gear swap just a recal on stock ecm 1st thing I would do is talk to a dealer to see if they can recal for rhe different tire diameter and or gears and and what gears they can recal for I know in a 2017 they won't do a recal on a gear swap if not available from factory FYI some tire shops can do the tire size recal again just not sure on a 2016 when I changed my gears in my 2010 I used a rpm / speed inline calc to pick ratio I wanted to tow st 70 and knew rhe 5.3 had to be over 2 k to have any torque 3.73 was not enough and 4.11 was a bit too much rpm went 4:11 and later switched to the 33 tire was perfect 68 mph at 2200. In 5th never any regrets towd for hours at that rpm trans does mot downshift much so trans never got hot rhe up and down shifting creates the heat Your newer 5.3 wil do better thanmy 2010 5.3 but your towing more wt so IMO tow aroynd 2200 theses new engines can handle the rpm Hope that helps
  14. You need to change ring and pinion in both front and rear diff not a big deal but you need to have the ecm reprogrammed for the new ratio not sure if a 2016 can be done by dealer you may need to find a custom tuner I already had a custom tune in my old truck so easy to do when I installed 4:11 now have a 2017 6.2 so not that easy to reprogram so sticking to stock tire ht as I tow my car trailer alot
  15. Your gonna need alot of throttle to move that load with 3:42 and 33” tires cruising rpm not that big a diff but the starting gear ratio is not great I towed 7000 lbs with a 5.3 cc 4wd and a 6 spd with 33” tires but changed to 4.11,gears towed in 5 th at 2200 at 68 mph if you dont have alot of hills or headwinds might be ok but for 33” you need min 3:73 to perform decent IMO. KEEP THAT 5.3 above 2k when towing find an online gear ratio / rpm / speed calculator and plug in you actual trans ratios by each gear then you will see the difference with 33’s
