Try a 12:1 disc and lean out the VAFC -40% narrow throttle, for full throttle settings - take it to a dyno. Good Luck

You don't even need the fmu, but if you want to use one go with a 4:1 fmu and lean it out from there. A 12:1 will be overkill.
make sure you take it to a dyno before making any changes, get your airfuel ratio rite.

yeah, don't use a damn fmu, you'll have plenty of fuel with the dsm's and a -40% trim for about 10-12psi. sell the fmu and get an MSD BTM.
