I have a 2012 gmc sierra originally with a 4.8L engine and a 4l60 transmission. The engine blew (all stock). I swapped in a 6.2L with a 6l80 from a 2009 yukon. I put in a T42 control module (to convert the 4speed to the 6speed). I put in a basic tune from a Diablosport tuner and started the truck (high rpm) started a fire under the truck burning through the t42 wiering harness and frying the tcm inside the 6l80. I replaced the tcm with a programmed ecm by the t42 manufacturer with knowledge of all this information. (This is where i am now)
My plan is to put the yukon ecm with its stock software and oem tune in the truck and run it. My issue is that shops around me are telling me they cannot dyno tune gm vehicles anymore do to legalities. I am not a certified dealer so i cannot get the crm software to program it myself.
Does anyone have a diablo sport economy or stock tune for a 2009 slt 6.2l 6l80 extracab 4×4?
(2007-2013 shouldnt be an issue since its the same body) gmc slt (slt comes with this engine and trans configuration)
I have the diablo sport trinity platinum tuner so there shouldn’t be any restrictions.
Thanks for any information.
