I am thinking of doing the 3.5" Air flow sensor (AFM, aka HFM) mod on my 2.8
Everywhere I look, it seems like it is only done on M3's
I read somewhere that the torque curve is affected so that the peak torque is reached at higher RPM. What do you know about this?
Is there any reason why I shouldn't do it on my car?
I am planning on doing 3.5" CAI and M50 intake manifold
If I cannot get software specifically for a 328 w/ a Euro HFM, will I still experience decent gains? I don't think I am ready to pay for custom software just for that, and I haven't found a place that has HFM software ready to go for the 328. I post this here because I don't want to call Turnermotorsports if I am not ready to buy yet.
