Car dies, I'm out of ideas.

[Three02much]

Mods.. 347 stroker, 24lb injectors and calibrated maf, ford motorsport svo upper and gt40 lower intake, patriot 185 heads, comp ultra gold rockers, comp 555/565 274 xtreme energy cam, comp hydraulic lifters, no egr, no secondary air injection. 80 mm throttle body, exhaust , adj fp regulator, tremec tko, 390 gears. car ran good and idled good, no problems, fuel pressure set at 38 w/ vaccum off. 10 degrees base timing, properly set tps. I know i need a chip but i was able to get the car running great by adjusting those things, it was just a little bit rich. before this it had a 347 with everything stock except no egr, and no secondary air injection, removal of those didn't seem to effect the car negativley at all.
after these other mods the car ran fine except for the occasional highway miss for 8 months.
