  1. Too many engineers and their "bright ideas" working at GM right now LOL.
  2. The 20"s are what hurt your payload. The load index is 121 vs the stock 18" size that has 124 load index tires. Trucks with 18" wheel/tire from the factory have higher payload on the door tags. This is also why 1 tons only came with 18" wheels 2011-2019.
  3. There is no manual release...not without opening the tonneau (if you've got one) and then opening the tailgate access panel that is at the top inner side of the gate.
  4. Trade it. Not worth it on the new T1 trucks.
  5. Reading most of this thread, its in regards to 8 speed shudder. a ZL1 6 speed converter won't fix an 8 speed issue. That video is ZL1 converter swapping a 6L80 in a Chevy SS.
  6. So...you put a wider, more aggressive and larger diameter AT tire, that depending on which one you picked (P or LT) is 11-21 pounds heavier per tire and then are wondering why you've lost MPG? Have you gotten something like a Hypertech or Superchips device to re-calibrate your speedometer as well for accurate readings with the larger diameter tires? 31.9" stock vs 33" that's 2.5mph so when it reads 60mph on the dash, you are really doing 62.5mph.
  7. Well, kinda. What size are you running I guess might be a better question for me to have asked. I took a stroll on Nitto's site at the G2. In stock 18" 265/65R18, they offer an LT E load or a P metric extra load. In a 275/65R18 (a popular stock upsize) they are also a P metric extra load. The 20" 275/55R20 and popular upsize 275/60R20 are both a P metric extra load. P metric XL are still a P metric tire, just with a bump in load index for more carrying capacity. They are not of the LT type tire. So, if you are after a "Chevy shake", the P metric tires should have no more than 15lbs of road force per GM PI1354I: Information on Vibration Analysis and Diagnostic. Otherwise, GM's limit on P tire on light truck road force is 24lbs or less.
  8. Are those tires an LT tire or P tire? Makes a difference in GM's spec for road force testing for the "Chevy Shake" diagnosis bible they have.
  9. They definitely don't last "forever". Typical life, if done properly can range from 3-6 years depending on the product used and maintenance/care of the vehicle after its been coated.
  10. They've switched tires and size since your truck. 22" get 275/50R22 Bridgestone Dueler Alenza HL for "efficiency" now.
  11. Blue Driver. https://www.bluedriver.com/products/bluedriver-scan-tool They have what they call "enhanced diagnostics" that can read ALL the OBDII codes in ALL the modules it can find for many brands, including GM. I have two of these and they will read all modules, from ECM and TCM to BCM and HMI and more.
  12. I'd have the codes read to really see what is going on, but cruise not working and not coming out of park could be caused by the brake pedal position sensor. The sensor is related to cruise control as that is one of a couple options that cancels the cruise control. As for the coming out of park, that sensor is used by the Body Control Module and Engine Control Module to see if the pedal has been applied or not in order for the BCM to then power the shift interlock solenoid and let you shift out of park.
  13. And that is why its always stated by the manufacturers and the EPA, "your results may vary". The estimates are all averages. The price in fuel used is an average as is even the gap for $$/gallon. Just in a 20 mile radius of me the gap from 87 to 93 octane can range between 39-55 cents.
  14. If these trucks still were just only 6 speeds, the 6.2 has the advantage over the 5.3. GMT-900 days and early K2 the 6.2 was the hot rod for sure. 8 speed on the 6.2 for 2015 made it more of a gap. Late K2 and now T1 however, I think the transmissions have started to make the gap a little closer or at least the 5.3 much better to drive with the 8 or now 10 speed transmissions. Not a T1 test, but here was pickuptrucks.com's shootout of max tow 1/2 tons. The 5.3 NHT with 8 speed was 1.17 seconds slower to 60 than the 6.2 NHT 8 speed. 1/4 mile was .9 seconds slower. Both trucks had 3.42 gears. Kinda shows you how close the two have gotten with the same gearing and transmission. https://news.pickuptrucks.com/2016/01/texas-truck-showdown-2016-acceleration.html Here is some T1 data to show that its even slightly closer now. 5.3 8 speed 3.23 - https://www.caranddriver.com/reviews/a25016363/2019-chevy-silverado-1500-by-the-numbers/ 0-60mph was 6.1 seconds, 1/4 mile was 14.7 seconds. 6.2 10 speed 3.23 - https://www.caranddriver.com/reviews/a24851287/2019-chevy-silverado-pickup-high-country-by-the-numbers/ 0-60mph was 5.4 seconds, 1/4 mile was 13.9 seconds. So a difference of 0.7 seconds to 60mph and 0.8 seconds in the 1/4 mile. So to put a spin on this, is 0.7 seconds to 60mph and 0.8 seconds to the 1/4 mile worth $2495 and 30-50 cents/gallon?
  15. GM floor liners > Weathertech and Husky. I had Weathertech in my 2015 HD and in my 2012 extended cab. The driver side held in place fine, the passenger side didn't come with the Weathertech provided anchors at the time and would never stay in place. They were smooth on the bottom too, no little rubber nibs to grip the carpet. I had the GM liners in my Colorado and now in my 2019 old body Silverado. Much better mats. The rear being a two piece doesn't even bother me as it covers the floor more properly than the Weathertechs did. And the GM ones have the little nibs that hold the mats in place, no need to install extra anchors anywhere. Driver side has the same style anchors as the factory regular mats that just snap in place.
