    2015 GMC Denali
  1. As promised! Picked her up yesterday. With the stock gearing it pulls really well in Tow Haul. Without tow/haul I can feel her back there until over 80 km highway. What is my safe trans temp range, as long and I'm on the gauge? I was hovering between 90-95 towing around town yesterday.
  2. I've decided to do a gear swap. My mechanic recommends 4.10's, I noticed a few of you recommend 4.56. Which one will be a better gear? Isn't a 4.56 more of a mud bog/drag gear? I wan't to make sure I have the power to pull but also have a comfortable truck to drive.
  3. I couldn't either. This is her and other than this issue I just came up against, couldn't love the truck more.
  4. Need some advice. I have a 2015 Sierra 1500 Denali with the 6.2, 9" Lift, 37" tires and 3.23 gears. All the modifications were done by GM so should be done right. I just bought a 7000lb travel trailer that's been our dream. I also bought a weight distribution hitch with sway control. I really want this trailer, really love my truck and don't want to have to change the gears. How much am I pushing it? Does the 8 speed transmission compensate enough for the tire size? Any other concerns? Thanks in advance!
  5. Thanks for the post. I was also wondering the same thing. Have a Denali with 37's and just bought a 7000 pound dry trailer. Was going to use my Bully dog to tune for 94 octane but at $1.52 liter/$5.74 gallon not sure it's worth the change.
  6. Yes AFM. Thanks Sierra Dan
  7. With my mods the main one being 37 inch tires should I disable my FMS? I notice the only time I can get the truck to switch to 4 cyl mode is down hill or on a flat with steady pressure no acceleration. Am i seeing any benefit? Is it harmful to the engine to always be in and out of modes on the flat? Thanks
  8. Sorry if this has been covered. I have a 2015 Denali with the 6.2, 9" of lift and 37" tires. I have looked in to a custom tune and the cost is around $400 which brings me to the idea of purchasing something like a bully dog to have the extra features and be able to customize myself. Am I on the right track? Will I see noticeable gains? Is it worth the money? Future plans are CAI, LT headers, high flow cats and Flowmaster 50 series catback.
  9. Thanks for the reply. If I went the SC route how many pounds would you recommend? Does it take a lot of life out of the engine? Big increase in heat? What is the issue with the 8 speed TCM? Sorry for the questions I’m new to this year of truck. Sent from my iPhone using Tapatalk
  10. Thanks EaglesZ71 that’s great advise. Those are impressive numbers! Not a huge loss in MPG either. Sent from my iPhone using Tapatalk
  11. Truck has the 6.2 L86 with the 8L90 transmission. Question is are the benefits worth the risks to the engine and components running around 5lbs? Will I have a huge loss in MPG when my foots not in it? Is the gain worth the money? Sent from my iPhone using Tapatalk
  12. Need some help guys and girls. I always wanted to stay gas so lets please avoid the diesel vs gas argument. I would like to add a little extra power for around town as I'm now rolling on 37" tires and when towing my 5000lb travel trailer. Was thinking of adding the Whipple SC to my 2015 Denali as GM will still warranty my truck with it installed. I will see a pretty decent increase in HP and Torque. Has anyone done this? Any words of advice? Thanks
