I can't seem to catch a break with this damn truck I had it running/idling with (vve/vt/maf/vvt disabled and everything else) dialed fairly close a few days ago. Now randomly it's just all over the place and last night it was leaning out down low unless I go crazy trying to bring it up with maf. its just not right and it just sounds like ass the idle sounds like buzzing/fluttering theres no lope like hyper speed regardless of target rpm it start up less rapid it quickly revert. Spent 36 straight hours writing files starting over tuning step by step the whole nine tried this in every way or revert to a entire stock file engine/trans minus disabling DOD/COT with or without disabling DTCs corrected for my application no change. While it will run it's just pitiful and frustrating to come this far and have all this money tied up in project that’s my DD. I tried dialing in my o2's today since i have p015b p015d codes permanent post cam install had LTs headers on long before this with the rear o2's disable did not have this issue with the upstreams at any rate its acted right with these present there's no leaks. I did update my firmware and downloaded the latest vcm suite thinking that may cause random issues. Check for post maf air leaks/vacuum leaks none went thru the harness/fuses the trucks got 58k on it the fact that the codes are simultaneously present its unlikely they both failed but I have lost communication between the mpvi2 and the pcm code pop up I don't think the e92's fail all that often. Either way it's a FBO LT's none catted y l86 mani-throttle/ 22x/230 cammed (w/ 0 degree limiter) DOD deleted L83/6L80e 2018 silverado. All bolt on were on long before the cam-dod delete as stated it has run right with no problem before and after now randomly started this out of the blue tuning doesnt seem to really to be doing anything at all as of right now. I know on thing that its mechanically in time arrow to dot 100% as i pulled it twice. Please help im about to drive this thing in to a lake.
