it didnt do it when i firts put it on there, im using the pyro and gauge on the h&s but yea i let off and chilled out for a while right when it done it. i wasnt even on the gas like i just stomped on it and it did that so i let up immediately.something isnt right tho. its before the turbo not after. im calling h&s today
I always run my truck this hard. I use wild because it's giving me the best fuel economy. I'll only keep it till 90,000 then trade it in on another. This is my second one this year. First one only lasted 5 months till it had too many miles. If I blow it up before that I'll coast it into a tree.
The new LML will run up to 1800 degrees if held WOT for extended periods on a Hot tune. If you are seeing over 2000, you have a pyrometer problem. Probably the PCH board that the pyro hooks in to. Give our tech department a call to see if they can help you diagnose any issues. 888-628-1730
You guys that are scared of 1700 degrees, this is normal for these new trucks when tuned. We have hundreds of dyno runs on the LML, 6.7L Cummins, 6.7L Ford, and 6.4L Ford that we purposely hold them at over 1800 degrees to test the durability. NO failures at our facility to date.
Many have this misconception that anything over around 1300 degrees is doing damage, not true. A stock truck will run these temperatures under the right conditions. With more power comes more heat, fact. EGT readings are a great reference point to start diagnosis for problems, or to see the range your motor is running in. Personally I believe that too much focus is aimed at EGT readings. There are a number of equally important factors that come into play, and a simple EGT reading alone tells next to nothing when other parameters of the engine operation are unknown. Just a little food for thought!
