ok here is my situation,at normal driving conditions car runs great, when i put the pedal to the floor and runn it like that for a second the car stalls, and stutters, and i have no throttle response till i let off.

i have a 98 eclipse spyder with a 16G turbo., 3inch downpipe, BOV, fuel rail, fuel pressure regulator, 550 cc injectors, fuel pump, greddy front mount intercooler

Is it tuned?
Check o2 sensor, knock, coilpack, plugs, wires, CAS...start with the cheapest/easiest to check.

sounds like fuel cut. Do you have any fuel control for those 550 injectors? Which pump, 190 or 255? What is base fuel pressure? need more input to make an educated guess.

 

[Coldandafraid]

sounds like too rich to me... you got an afc controlling those injectors?

 

[lmill83]

ive got a afc c ontrolling the injectors, its a 250 fuel pump, and i have the base pressure set at 41psi

It could be your mass airflow sensor.
