Default vafc is kinda shitty but it runs

I installed some rx7 injectors with the resistors yesterday and when i was trying to make it idle right i had to take it all the way up to -15

i thought i was supposed to be ok at -40 but i guess not
and from 1000 to about 2000rpm the engine doesnt like to stay at a constant speed

1000 > -15
1500 > -35
2000 > -41
3000 and rest > -42

So basically, instead of fixing what is probably a vacuum leak, you're drowning your cylinders in fuel so it will idle? Hrm..
