Question sd injector dropout problem

hi running sd rom id 96533706
car is a evo 8 260 has a billet gt35r forward facing kit and 1000cc rc injectors.

i purchaced a omni 4 bar map and wired it along with a gm temp sensor .
i wired temp sensor to pin 77 and map to pin 73 as i am supposed to

the map sensor i calibrated in sd map sensor and ve calibrations to omni 4 bar etc
i have scaled injectors best i can so far .

the problem i am getting is injectors drop out at around 3 psi of boost at around 3600 rpm , i have logged it and injector pulse width drops off fast and then comes back also obviously the duty follows it . it happens all way up the rpm scale they keep dropping out , map reading etc is smooth and tps is around 45 % and kept steady , they even drop out while being revved parked
does anyone have any idea to help me .
have i missed something ?


i am going to try another rom 96260009 tonight with a e9 map sensor i am going to borrow with scaling for e9 sensor

thanks for any help i need to sort this asap or i am going to pull my hair out haha

I see similar issues on my MAF car in the same area. Feels like the car is misfiring or fuel cutting, or load cutting. The rest of the pull is fine.
