Yes, I may have overdone it with the 30 lb nozzles, but I was looking at boost in the future and that 25% bigger on nozzles would be easily covered by going to a bigger MAF unit. Looks like I'll probably switch my motor back to the 24's. There is an FMU on the frame(8:1 fuel boost/air boost)(vestiges of speed-density). I just never saw an fmu and maf get along ok. I wonder if the 24# maf off a 4.6DOHC has nearly the airflow/volts curve to run a 5.0's ecm with 24's or... . The home-made maf tube out of pvc was an effort to alow for future upgrades. I, with the .650 i.d. sample tube,(labelled as a "30#-76mm" application) may just need a bigger tunnel for the maf. Is that possibly better with an 80mm, an 85mm pipe around it?? Definitely not as linear as it ought to be, (or curved). Back to baseline stock and inch my way back into trouble again, I guess...BT
