[QUOTE="6699Mustangs, post: 16824485, member: 204048"] Yes. returnless fuel system. That fuel pump is designed for an upgraded fuel system on a 99 Cobra. Here is the series of events once the car was complete. Tuner stated car was running fine but low pressure. Around 30psi. Also the alternator was fried. So he installed new alternator and fuel filter. Filter was probably original. Said the pressure came up and re-tuned based on higher psi. Then it started to spike occasionally. Said to drive a week and maybe it figures itself out. Drove a day or so until transmission started grinding. Parked it until I could use neighbors lift and add fluid. Transmission ok. This morning I drove it and it stalled a few times because the spike floods it out. AFR is all over the place and rarely at a safe level. Mostly running rich. Think this AFR pegs at 17 and it stayed there for a while and ran rough. No rhyme or reason to any of it. Idle, under load, seems mostly in 3-5 gears. Also curious as to what boost readings should look like under idle, normal driving and acceleration. I'm not getting into high RPM because the motor is new and I need to break in before WOT. [/QUOTE]
