Has anybody had problems running a FMU for fuel management and at only 7 psi?

A few years ago I ran a fmu and 8psi on my h23a with no problems. I wouldn't go any higher then 9psi on a stock block if this is your daily driver and you want the motor lasting for a long time.

12:1?? I'm going to boost about 7-8lbs only. I'm contemplating on whether I should go with the VAFC hack or a FMU. This will be on a daily drivin h22. So...VAFC hack or FMU??

 

Yep 12:1.

I would prefer the AFC hack over the fmu anyday... given that you actually tune it for the hack instead of entering in random %'s people tell you that 'should work.'

 

should I go with a 12:1 FMU AND VAFC hack or is that just too much? As of right now I have a Vortech FMU and 6btm that I'm going to use. Should I run all 3 at the same time?

 

The VAFC hack does away with the need to increase the fuel pressure; so an FMU w/ the VAFC hack would be worthless.
