Would a FMU be good fuel management for t3 pushing 8 psi on a stock D15b7

 

Absolutely NOT. FMU's are not good for that much psi. I don't think they are good for anything and would never use one. If you do go with a an FMU I wouldn't exceed 5 psi. If you are new to this please look into chipping your ECU.

 

I ran a FMU for 2 years at 6-8lbs with no problems. Is it the best way to go? No. Will it work? Yes.

 

is a fmu a good idea
no
will it work for 6 psi
yes
do I have one that I can sell you cheap
yes
pm me if you want it

 

IMO the FMU is a better solution than the Hack.

I would however recommend looking into getting your ECU chipped or chipping it yourself. Let me know if you need any help with that.

Sell the FMU on Ebay, buy an ECU (or chip the one you have if possible) and chipping kit and you arent out any money.

 

FMU is so dumb. ur better off just taking the stock fpr and crushing it in a vice.

j/k dont actually do this

 

if you plan on upgrading and dont have money its a good thing to have sittin around to use for a while but def upgrade

 

Fmu's work for simple applications but with so mnay options like chipped ecu's there is really no reason to go the route. If you are set on it make sure you have an upgraded fuel pump. Most fmu's set ups fail due to the high pressure the fmu requires and the factory pump cant keep up causing a lean condition.
