M30... no power
Ever since i bought my car, it revs and accelerates as it should from 1000-3000 rpm, but after 3500 RPM, the car completely dies and it will barely rev to 5000 rpm..

P.s: the car had a full tune up and pretty much everything on the engine is new.

Any help ?

AFM contacts worn, I had similar thing on my M20 AFM. Perfect up to 4k, then just falls flat on its face. Open the cover and make sure the pins are in contact throughout it's entire range of motion.

Ill check it out tomorrow , but if i do end up needing a new AFM, would the Miller MAF conversion be a good option ?

Thank you

I put Miller MAf about 2 years ago (previous, not tunable model without WAR cheap). I think it's good for the money I paid. More feedback is available at
