Excess clatter with EFI live
I have a 2016 GMC Sierra, CCSB duramax with EFI live tuned by Kory. Full delete. Installed everything this summer. I have ~26,000 miles on the truck, and about 3000 miles with the tune
I've noticed now that it is getting cooler that the truck clatters more when the engine is cold then it did bone stock. Its not bad but I notice it. It mostly goes away when it is up to full temp, but not fully. Switching tunes seems to make little to no difference in the clatter. I keep my tunes between the stock tune, tune 2 and tune 3, NEVER tune 4 or 5.
Is this typical for a deleted/tuned truck? I never noticed it with my tuned/deleted LBZ, but I was using a PPE tuner for it. I am running injector cleaner through it now and it seems to have helped, but it hasn't gone away completely. Any input would be helpful thank you.
