so im working on a 2009 sierra 1500 that had a blown LH6 5.3 and a LY2 4.8 was put in. i found a stock 2009 4.8 file in the tune repository and copied all the data from the 4.8 file to the file I read from the truck. I also disabled DOD. it runs not bad, except under acceleration on the highway it will go into open loop sometimes and then it falls on its face and stabiltrac light comes on, shifts real hard etc. the injectors were swapped from the 5.3 to the 4.8 but i did some looking and they are the same part number so shouldnt be an issue. both engines are bone stock so no mods to accommodate for. is this just a matter of need to tune vve and MAF? or is something else going on?
attached are a log, the file i have in it and the 4.8 file i referenced. it happened close to the end of the log where he did a pull and the all the way to the end.
any help would be much appreciated, thanks!
