you need to use map 6. but you obviously need to make sure everything else is looking good before and double check there aren't any boost leaks.

U need to run the appropriate back end flash (and have the appropriate fueling upgrades) for E85 mixes. Do you know what map 6 is? Yes you need to adjust it via your laptop/USB it is the user adjustable boost curve map.

Yes. JB4 MHD flashes are available from http://www.n54tech.com/forums/showthread.php?t=29236 for use with MHD app. Flash under JB4 in menu.

If you want to run E40-60 you would need:
1.the MHD JB4 E85 back end flash
2. Fuel-it stage 1 (in line) or stage 2 (replacement) low pressure fuel pump upgrade.
3. For inlets adjust Map 6 to model Map 7 (19 psi peak) but without the high rpm boost taper to start with. If you don't know how support at BMS or a number of forum guru's can help you out.

You beat me to it! LOL.

I was reading the thread to see where can I insert... "JUST CONTACT TREBILIA" on the other forum.

He's a good guy, excellent tunes and might be the only one with enough patience for a noob....
