  1. Replacing stock tires

    +1 Michelin defenders. And if you trailer get the load range E that can air up to 80psi for better load stability. Aired up to 45psi they get good mileage on highway commuting
  2. Catch Can Skeptic

    So you're saying that a cigarette filter that visibly traps tar does NOT reduce that amount of tar from getting into smokers lungs? To deny that a catch can reduces the amount of gunk that is fed to an engine denies reality. The smoking analogy was not meant to address how much gunk is good or bad but that sucking less into the engine is definitely the more desirable choice to keep your engine from getting smokers cough. Like some others here that have actually seen deposits inside an engine ...it does occur and cannot really be denied. Back when dumping 104+ octane boost in gas was a thing. I can tell you that stuff would coat the combustion chamber and valves with deposits you had to chisel or grind off. and that was a small bottle in a tank of gas. Engine oil with its additive packages is no different and burning it does not reduce it to nothingness. At work I sit next cubicle to a ~68 yr old chain smoker. he looks like he is 100 but is still alive by some miracle and received his 45 years on the job award today. Some years ago I sat next to a pretty 28 yr old young lady with a young child that also smoked. A couple years later she was dead from lung cancer. So yes the amount of tar a smoker dumps in their lungs is not deciding variable getting cancer.
  3. Kennerz, I was talking about engine coolant thermostat and not transmission thermostat. From what I've heard the 160 degree engine tstat is too cold and will cause problems for closed loop operation. 180 should be lowest you go. The 196 is still way better than the higher one the truck comes with and the massively high engine, IAT and under-hood temps that go with it in the Arizona summer where i live. Some people are removing the thermostat from the transmission and not replacing it. A turbo 700r is vastly different to what we have now. Even using the recommended GM fluid there are issues and they are working to reformulate it for better operation. If you want to experiment with other fluids and let us all know what you find i'm all ears.
  4. Catch Can Skeptic

    ...Its like a guy chain smoking cigarettes every time he drives. He may or may not get cancer but if he sucks those cigarettes thru a catch can the odds of him getting cancer from cigarettes will be a lot less. At the very least my engine wont have smokers cough as it ages. ...You all can smoke them any way you like. :-)
  5. Sorry but everywhere i have ever seen E85 it was not less than 50% the price of regular/premium. usually 70%-80%. it sure seems to me the corn sellers and fuel companies know exactly how many miles you get per $ you pay and it all equalizes out E10, E85 or diesel
  6. FWIW, I put the summit 180 degree in about 9 months ago. I believe it is Summit branded Jet thermostat and I also had read that the seal can become detached and the stat not fully close. The rubber seal appeared to be thermally fused onto the disk very well. I just traveled 2000 miles to Dallas and back and scanned using hp-tuners some of the way and the temp stays rock solid at ~186 degrees. If you don't trust the Jet get the gm 196 one and use an old Chevy trick and drill a small hole in the disk. I believe a 1/8 or 3/16 hole is all you need to allow a bit of bypass and drop the temps. I don't think GM makes a 180 for any of the new motors as they are supposed to run much hotter.
  7. by putting them boots down you're not adding the weight/mass of the shocks body to the axle. Having less unsprung weight is a good thing.
  8. The wife's 18 CTS-V gets about 23mpg if you keep your foot out of it. I would suggest that that engine will make so much low rpm torque that it wont be bad mileage at all as long as you soft toe the pedal. Just tip in the throttle and let the trans do all the work.
  9. Do you have magnaride shocks? it is my understanding that the damping is variable and that changing the height can throw them way off. Last guy with a similar question it was riding like stone.
  10. I'm not buying the hygroscopic bit. when up to temperature the fluid will get hot enough for any moisture to vaporize and leave the same way it entered. And mine started the chuggle @~25k miles and a few weeks after returning from a 5500 mile trip towing a huge trailer. The trans would go over 200 degrees at times and i live in dry hot Arizona with almost no moisture to condense in the trans.. I don't believe the chuggle is causing permanent damage. The reason is that the issue itself is a clutch that is having trouble maintaining a consistent slippage %. So it is meant to be slipping and it is modulating between too much and too little that is all ...it just gets "Grabby" not really destructive. slipping the clutch smooth and consistently is not as easy as it sounds. The grab point is at one pressure and the slip point is at another. The computer has to control the clutch actuator between these two points without you feeling it. The properties of the fluid are being adjusted to hopefully address some sort of breakdown in the fluid. So an increase in Viscosity and maybe a bigger dose of friction modifier? I figure the fluid may just last longer than before to get GM out of the warranty period.
  11. At the end of the day it is a personal choice and I respect the ones voiced. However IMO you can address the 6.2 shortcomings for heavy towing like mushy springs/payload and have a great DD. If you go 6.0 that gets horrible mileage and rides like a brick when not towing you cant fix that.
  12. the 6.2 with a trifecta tune can run regular gas and not lose much performance due to knock. Payload of a 1500 can be increased by adding helper springs or IMO a better option airbags. I lowered/leveled the back ~2" so once the trailer is hitched I air up to original leveled ride height. So @ ~60PSI they neutralize my trailers tongue weight and so restore full payload and it rides like a dream. The airbags aired down for no load and the truck rides great for dd.
  13. a truck rated to pull X ...will pull X plain and simple. IMO The 6.2 is a beast and with some suspension tweaks will tow very confidently tp its max.
  14. If you tow a lot # and want to have a confident feel when you do it with a 1500 max tow. Bilstein shocks at least in the back. Air bags pressurized to regain normal ride height once loaded. Eibach rear sway bar WDH for bumper pull Bumper pull, Make sure your hitch receiver fits snugly. Mine was very sloppy loose so I "Fixed" it ...nice and snug now for minimal sway The shocks dampen the bouncing, the Airbags efficiently support the additional load, the sway bar stabilizes the rear and the WDH moves the weight forward of the rear axle. other than the TT trying to sway the truck it is rock solid pulling at its maximum rating 12k+ lbs and bumper pull. 5th wheel will more inherently easier to achieve stability.
  15. I got the S-Type on my 6.2l and the V4 sound was not that noticable. Because I tow distances though and the engine is working a bit harder the sound pressure level was bugging me a bit during a trip. I followed a suggestion in another thread and had a Borla stubby muffler welded in front of the S-Type muffler and it took the edge off of the towing sound. Very happy with it now.
