HP tuners offers a custom operating software for the 98's that efi live doesn't. You can run up to 14.7psi and be able to tune for it. I believe it goes up to 210kpa. You could also do what others do and do a computer swap and repin the harness. You would also have to do a segment swap to get your gauges to work.

Your gonna need at least an 80 with 8-10 pounds of boost on e85. Go to rceng.com and figure out your injector size. Instead of using the BSFC .60-.65 use .85-.88 to be safe. or take .65 times .35% = your BFSC number.
