Sometimes when i drive i feel like i'm not getting enough fuel. I was wondering if my 12:1 FMU is going bad or something. I've had it for 3.5 years now. ???????

Not sure how you know you are not getting enough fuel.

Fuel pressure lower, egt higher, hear knock, datalog and see timing advance drop, fuel trims not at zero on a wot pull.

If it is just seat of the pants feel, then you are guessing that is what it is.

Check the rubber gasket that comes with the fmu. They can get a small hole and not allow fuel pressure to rise like it is suppose to. My suggestion is to call Vortech and order a new one.

A new gasket also comes with the recalibration kit if you ever need to change out disc/rings with larger injectors.

It could be your igntion system also. Check your plugs, wires and coil pack. I think your ignition would wear out before a fmu.

How many times have you changed your fuel filter in the last 3.5 years?
