anyone with ls integras....whats nessicery as far as fuel upgrades required to run 7 psi....???? thanks

 

something like zip's smc or an apex'i safc with some dsm injectors is a good, cheap fuel setup. take it to the dyno to make sure you're around a 12.0:1 air/fuel ratio. Stock ignition timing should be safe for that boost level.

 

what if you want to put some 440 cc with an air/fuel controller with the fmu?
