  1. Putting E85 in the 2014 5.3 has shown better results than any stret ecu/tcu tune for 93 octane so far for me. What I plan to do , is leave a street 87 octane tune in with good tcu tune and then go BIG on the E85 fuel tune. It is nice that GM gave us a nice starter race tune for E85..
  2. Anyone running the Intune on a 2014 5.3? If so, have tried the economy tune and notice if DOD is engaged longer on the hwy? MPG improve? I wish they had a tune for E85, since our maps are pretty aggresive for that fuel.
  3. I have some vibration and chatter as well and seems to be the rancho shocks with the LTZ package. they are damn smooth off road but suck on the hyw and I have same rough ride in cold weather, until tires/shocks warm up. wish I had the non z71 shocks that are twin tube VS mono tube for hyw ride. Also have a vibration from maybe the exhaust at higher rpm , just before the shift under heavy throttle.
  4. My z71 package is pretty stiff as well and ended up being stiffer than the std package truck I test drove. I had to have the Z71 grill, so shocks I can change back to twin tube for smoother ride at anytime:)
