how do you ajust the fmu??
ok my supercharger works great but the problem im haveing now is when i hit about 4200-4500 it stops and chugs i think that its not enough fuel i have a 255 pump with a fmu and 19lb injectors if it does that i think its a fuel problem how can i ajust the fmu and or do i need bigger injectors?? im only pushing 6psi
It depends. do you have a vortech super fmu? I assume not becasue it is pretty self explanatory if you have one. If you have a vortech basic type fmu, there is a kit that has certain size disks for the different ratio fmu's. The smaller the disk, the smaller the ratio. I think the disk kit is 30 bucks.
I personally wouldn't run 19's on a boosted car even with an fmu. I've known way too many people getting too lean-a-condition that way, and killing their motor. Make sure it isn't pinging.
