I have dsm 450cc injectors inline pump and afc and fmu , what ratio disc should
i get. vortech tells me 4:1 what do you think?

 

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.
