I have a mac 73 mm maf, intake, bbk 70 mm throttle body, and ported and polished explorer upper and lower. I just put on bbk equal length headers, bbk o/r h pipe, and flowmaster original 40's dumped. I pulled my plugs in the process and I could tell I was running a little lean. I havent felt or heard it ping though. I have a walbro 190 lph fuel pump 24 lb injectors and calibration tube. I can't hear anything but the exhaust now, so do you guys think I should put the fuel upgrades on or is the stock setup sufficient for what I have on? I was going to wait to put the fuel upgrades on until I put the gt40 heads on but I don't want to run lean. If anyone has some input I would greatly appreciate it.
