I just installed 24lb'ers and now I can't run my fmu.I was told the stock fmu is for 19 or 24lb'ers ,I also put A c&l 73mm and lost 3 lbs of boost. I had a pro m 75mm and I was at 9lbs.The car runs good without the FMU but I think it's unsafe.Should I go with a 8:1 fmu , or with a fuel pressure reg. that is boost sensitive(1:1)?Where is the cheapest place to buy from?
