The AFM is what limits the system so before you go full standalone decide what your goals are. < 300whp mark the Rtek. should be fine. Read of it running cars with much more power but everyone complains AFM...wouldn't know much about it yet. I'm still trying to find one and My car is still under construction.
no matter how much someone will say something, i will always disslike the rtek.

heres why.

you are using the old stock mazda electronis that are notoriously bad in the rx7. do you want to still keep those? i bet you dont. the connectors are bad, the sensors are getting hold and worn out, and you dont wanna have to try and get used or new mazda sensors. trust me.

the airflow meter on the s5 isnt bad at all. its actually a proper shape. since its before the turbo, its not too much of a restriction.

like i said... dont waste time and money on slapping band aids on the stock electronics that drive the engine. go full stand alone, and you will never look back.

i highly recommend the haltech platinum sport 1000
