Yes probably more likely. Sucks it's so noise on the newer truck like that. That's gonna suck in like 20 years when I can afford one.
L5P tapping/knocking noise when coasting???

After a few calls and emails to GM, they still can't give me an explanation. They urged me to take it into the dealer if the drivability declined. I have an appointment with the dealer in Thursday to get the high idle flashed into the computer, so I'll run the "knocking" sound and the timing advance by them then. I have no problem putting up with the noise as long as GM will tell me "Yes it's supposed to be there, no it's not hurting anything, and it is there for 'this' reason." I don't think that's too much to ask(I'm not holding my breath though).
Let me know what they do to get the high idle in it. Dealer told me they could not flash the high idle in to it.
I've been trying to get high idle in mine for 3 years, ridiculous it's so hard to find someone that has the knowledge to deal it, I guess there's more to it than a simple BCM flash but I don't know.
Yes, different than elevated idle. It's that $200 option you can select when you order the truck, but it only cost $150 when you have the dealer install it. :screwy: Just set the brake and hit the cruise button, it will idle up to ~1200rpm. Great for winter/summer long idle times and in conjunction with the heavy duty alternator package.
When I asked the dealer about installing it, they did not know. What did you tell the dealer to have them install the High Idle?
I just told the service manager I wanted it installed. He called GM to make sure it could be done with the 2017 and he scheduled me an appointment. I'll take a pic of the paperwork when I get home tonight. They acted like it was a routine item, no problem at all.
My 16 isn't anywhere near as responsive as a l5p. L5p has much better low end and midmidrange response
This ^^ I'm liking my L5p more and more, it's pretty awesome in stock form.. Have about 3500 miles on now..
Just hit 1900 miles on mine. I'm loving it more and more as well. I came from a 2016 LML and I don't miss it at all. GM has really done a nice job with the L5P.
Still haven't heard back from the dealer regarding the knock. I'll give them a reminder call sometime this week.

Bought my loaded out 2016 a few months ago. I've been noticing a lot of concerns from both Ford and GMs new motors and trans. I'll give it a few more years for GM and ford to workout all the issues related to introducing their new redesigned motors and transmissions. I always recommend buying the last year of any model mostly because all issues have been for the most part resolved on a proven solid platform. Please please make sure to communicate with the manufacturer on all issues from the smallest to the major ones. Good luck

Except that they screwed up something on a batch of engines that get oil starved at startup and internal parts want to see the daylight.

Competition, pushing out faster 0-60, pushing power over quality. It's very well known that all new models introducing either new or upgraded power plants take about two to three years to work out the kinks. Duramax, Power Stroke or Cummins all have their issues but will work themselves out, eventually.
