Is there an E85 tune available for the LM7 engine? All export model Tahoes are LM7 engined, but I'd love to be able to use only E85, as it's a lot cheaper here compared to gasoline which is at $10/gallon..

You could ask BlackBear if he would do it. I'm sure they would.
If your vehicle is flex fuel, then you can already use the E85. If it is not flex fuel, you need to change out some engine/fueling components to accommodate the ethanol.

My vehicle is not flex-fuel, as no export models were. Plain LM7. I was just wondering, as I can install a piggyback conversion kit between the injectors and wiring harness, but with so many tunes available for these engines, I was thinking maybe there was a tune for running E85 on non-flexfuel engines. What components are the problem areas for making a E85 tune for a stock LM7? 
Junkyard parts are out of the question, as there are virtually no GMT800 platform cars to be found in any junkyard in Norway/Europe..

Off the top of my head , you would need a larger volume fuel pump, bigger injectors and tuning to be able to run e85 exclusively. To be flex fuel, an alcohol sensor would also be needed.
