the afm can be adjusted yes, there is a spring inside it that can be turned to make the flap stiffer letting less air in or loosend to let more air in.

This thread is another argument that will never be solved.
Can you run larger injectors without tuning? Yes.
Can you run an M30 AFM without tuning? Yes.
Can you run the both without tuning? Yes.
Will you be at optimum fuel/airflow ratios and performance? Doubtful, but I've seen crazier shit happen.

I run a 2.0 with M30 MAF and 325i throttle body and manifold, with a crap exhaust no O2 to fix any mixture issues I created,
So yes you can put anything on there if you just adjust the freaking wheel,
Also tuning back to the baseline with a O2 is just ridicoulus, you should adjust the wheel so that incase of ecu reset, the mixture and results will be the same as before the resetGunni

doesn't mean it's all working nearly as well as it could be.
for me, m30 afm + 19lb really opened her up on the highway. and moreso after the AFM was adjusted to stock tooth, not even moved two like most people do.
oh well. we'll see.

So let me get this straight. Increasing the fuel pressure through an afpr while on a dyno and monitoring the a/f ratio is the proper way to tune these mods (m30 afm+19lb injectors) or the bandaid way?
So no matter what mods I put in (excluding FI), the car should always run at a set a/f ratio? (i know it changes throughout the rpm range) What is this range? What is the maximum practical pressure to set the fuel at?
As time went on, the factory developed the car each year, making it faster, more comfortable, and capable of handling at higher speeds.
You don’t want this. You want the trickiest, most dangerous, oldest model you can find. Only then can you prove to the world that you’re a man.

Ok I know this is an old thread but I am interested in the m30 afm and 19lb injectors. So tell me if I understand this right. With my Jim C chip I will not need to dyno my car if I install the afm and injectors??? Please only reply if you are knowledgable on the subject and not if you just threw these things on. Thanks.

and then you can worry about fixing it.
Or. You can confirm you don't need to do shit.
Either way, it achieves an experimental result which tells you more about your car.

I still don't understand what the big deal is - are you guys who are running the afm and injectors without the afpr running 12 second quarters or leaving 4th gear patches? Does it REALLY make that big of a difference? And what about those who ARE running an AFPR? Aside from cold hard facts showing that an AFPR can noticeably increase the gains provided by larger injectors and a larger AFM, can anyone notice the difference on the butt dyno?
