SR20DET looking for more power - AFM limitations?

[Tommey]

I am currently running a GT2871 turbo , Injector Dynamics 1000cc injectors, Z32 AFM and e85.
It makes 472WHP and 640WNM @ about 2 bar boost.

Looking to upgrade to the GTX version of the turbo wich will flow ~80 more HP.
I also think i will go for the Bosch 1700cc injectors, a little worried about how nistune copes with them but i cross that bridge when i come to it.

I will also (if not already) probably max out the AFM, is this a big problem or is it possible to map further after it has been maxed?

Thanks for all input!

Once you go over 550hp then I suggest the HPX N-1 MAF sensor (we sell these on our site, or you can get from http://www.pmas-maf.com)
