LMM tuning help

[elmanny2020]

Hello hp tuning people, need help with my 08 Sierra LMM originally i was having a EGR insufficient code P0401 i was able to turn that off and i drove the truck for about a month and maybe 700-800 miles and now recently the truck is in Engine power reduce and also states cleaning exhaust filter. I have no codes at all with HP tuners and also with TECH2 i have no codes i cant seem to find what is going on. I was wondering if anyone is willing to look over the file and see if you can see something iam missing or that is incorrect i would appreciate it !!08LMMUPDATE.hpt08SierraLMM.hpl

Re-enable EGR. Do an EGR cleaning in the Tech2 function menu. Verify you have no CAI leaks (unmetered air). Check boost pressure against Baro pressure with KOEO.
