lshatch1.8

hey guys im gettin a full greddy kit and the guy says he was running it with an fmu 12:1 i know that they suck but ive also heard that there ok for 5 or 6 psi. So im wondering should i run it with the fmu till i get my 450cc and fuel pump and urbadata or should i just wait? also i have a stock fuel pump would i have to upgrade that if i ran 5 psi on the fmu. I know they suck but ive heard there good till about 5 psi let me know thanks alot guys

umm i hate FMU's, I have ran them in the past though and until 7 psi on my old LS motor it would run good and not lean out. If you are going to run a FMU i highly reccomend the walbro 255 hp. I would say just wait until you can get it tuned wit uberdata but if I was in your shoes and had everything else you would probably see a FMU under my hood just to be boostin but i reccomend getting it tuned with bigger injectors and that junk
