I am not the tuner but trying to assist where I can and learn in the process.
Background on the build is 6.0. 80e swapped. Walbro in tank. Decapped injectors. 2-bar map. 78mm turbo. All the fuel related stuff was done while still running the maf and original map sensor before the turbo was installed. Ran and drove like factory. Did the turbo, map, and went full speed density and have been fighting the surge since then. The initial startup seems normal up until about 15-20 seconds and then is starts surging, even up until 1500-1700 rpm. Roughed in the ve table to within -5 to +5%. Followed the gen 4 idle tuning guide with no change. From the research I?ve done I believe it?s either something missed as far as failing the maf because it almost seems as though no matter what changes are made the problem persists or something with the VE table. New to all the gen 4 speed density stuff and know there are tons of people here that have endless amounts of knowledge on this stuff and hopefully someone can shed some insight. Will be posting the tune file as soon as I get it later this
