I just picked up my FMIC. Its 26 x 3.5 x 6. I also have poly motor mounts. Stock fuel system right now. I got a good deal on the FMIC so that came first. I was wondering How far I can boost the 14b in my 1g gst, with a full exhaust. I know about fuel cut but Im just looking for a margin of were i can boost to. Also if anyone has a time slip with a similar setup that would be great to tell me what you ran.

Most people will tell you to stick to 15psi on the stock fuel system, then raise it to 17psi after fuel is upgraded and then around 19psi with the fmic....

BUT.... I would highly suggest using a datalogger to figure out your boost level. I thought 15psi was cool too until I got a logger and figured out there was something wrong with the stock setup causing me to run VERY lean .... even at stock boost levels (9psi).
