Do you have to use an FMU once you upgrade to lets say 370's? If so then an 8:1 should be used?
Thanks in advance,

A regula fuel regulator will always be used. I am just asking if the FMU is necessary and if 8:1 pill is the one to use with 370's.

it all depends on your car. I used a 6:1 with a special controller i designed to work of the map sensor. All cars will act different. So start high and work your way down.

An fmu will help provide a nice ratio at all rpms vs. tuning for top end or mid range. You'll obviously need a lot more fuel at 6k than at idle, so if you want performance everywhere you'll need the fmu.
