I am looking to get a FMU with the Walbro 255 fuel pump for my turbo setup but not sure which FMU to get. I was looking at a Cartech(BEGi) #2025 Boost Dependent regulator $190 shipped, or a Vortech 12:1 ratio for $124 shipped. Which would be a better FMU and what ratio should I be looking for? I read that the 12:1 is 12 psi fuel for every 1 psi boost... that seems like a sh*t load of fuel! Thanx in advance guyz.

 

Oh....meant to ask what you other Turbo SE guyz are running...... I am planing on keep the stock EFI setup for now...untill later down the road with more knowledge to step up to Haltech.

 

My Aeromotive should be here thursday, $132 from Summit.

A 1:1 ratio is what most people use.

Yea the stock T2 FPR will get over-run by the Walbro. A FPR upgrade will fix that problem and set you up for future fuel upgrades.

WOW...only a 1:1 ratio is needed when boosting? I thought it would require more fuel than that. So that 12:1 would be serious overkill!

 

pm web777 , he has a similar setup, im not sure what he has......i'd say at least a 12 to1 on a fmu setup with stock injectors....
