I have a supercharged 5.0 and have finally found what seems to be a very reputable Foxbody dyno/tune shop in Columbus, OH. Talked to the owner today and gave him my list of mods on my 90GT. He recommended I make some changes/upgrades before I bring the car in. As a few on here already hit on, I need to beef up my fuel pump from 190 Lph to 255 Lph and my 24# injectors to 42# or 60# (if price is comparable). This will allow me to do away with the FMU. I'm new to all this and a couple things. He mentioned something about 40# based pressure. No idea what this means, can anyone help? Few other things I picked up on from reading about the V3 SCi: I currently have a 75mm mass air meter. If I up the injector size, do I need to have the mass air re-calibrated? How important is it to upgrade my ignition system? I read where it would be wise to change plugs to 1 heat range colder than stock. I'll probably go ahead and do this since it will be fairly inexpensive. If you have any suggestions on what injectors to buy and best place to buy them (cost), let me know. Thanks!
