ok so i just put back in my basically stock d15 for a little and it ran fine at first. i had tuned it a little on crome and then one day when i step on it and only when i hit100% throttle my wideband will go all the way lean. thinking it was my tune i adjusted the tables and still no luck, so i swapped out the chipped computer for a completely stock ecu. still does same thing. runs fine around town but when i step on it it goes super lean but on decel it does cut the injectors which makes me think the map is working... any help would be great thanks and btw when i say lean i mean my gauges maxes out at 20 to 1 and with my aftermarket regulator i need 80psi for it to idle
