rough idle
ok so i just put in my reflashed ecu and started up my car. now it ildes really rough at times it will idle good. you can see vacuum is where it is supposed to be, around 15hg-17hg, but at other times vacuum will drop to like 9hg or 11hg around there. what could be the problem. could it be that when they reflashed it they set the timing incorrect or what? please help
other mods: vf22, walbro fuel pump, borla headers, helix up and down pipe, blitz cbe, hks bov, modded injectors, aem shortram intake what could be the problem?

Do you have some way to check your fuel trims?
