By the way, for those with intense knowledge and hardcore tuners, from mazda-speed.com website... > afm delete?
And if case you are more lazy than me by not installing a MesquirtingUKit, here is the reply from one of the users (mprhead5).
"It is my understanding that the stock AFM as you like to call it can handle a fair ammount of airflow/power. And if you get to the max airflow you can upgrade to the larger RX7 version relitivly painlessly.
It is my opinon that when tuning a car it is best to look at it from the standpoint of what can I do with what I have and not what can I transform it into. looking at it from this standpoint will save you a bundle of cash and usualy only cost you a few HP. For instance I did a 350.00 turbo upgrade and only have 10-15 whp less than others that spent 2K+. In reality the AFM is ok for your application. I had the figures at one point but I can't remember where. If it comes to the point where you are flowwing more air than it can support then you can upgrade to a the RX-7 unit for better airflow. as for the ECU end I would point you toward a E-manage since its well tested for your application.
the question is do you want to spend 1k or 3k on this car? With a 1.6l car on a greddy turbo I would be more inclined to say 1k.
BTW what mods do you now have installed? and what are your goals with this car in the long/short tearm.
add your mods into your sig if you can
for a greddy Kit I would advise
New DP ( I know somone makes em for the greddy kit )
E-manage and probebly bigger injects
thats all cheap stuff and will give you great perfomance without having to spend 1600 on an xede or 1200 on a link ecu.
If you want to go high end I think the link from FM is the big daddy of NA ECU options"
I went through all this discussion long time ago and once again the thread gets hijacked.
