its possible to hook the maxima afm to the stock airbox with a bit of modifcation, i did it for pedro, i have a scar on my left hand to prove it!
can't remember exactly what we did, but a few extra holes in the airbox and cut back the corrugated piping.
the best option though would be to install either 3" or 2.5" piping as the corrugated pipe is detrimental to airflow.
+1 the whole point of the tuned chip (for maxima afm) is so it can run on the maxima afm (no real suprises there). i had similar troubles when i wasz trying to swap a stage 3 chip in for a rb25 afm no end of trouble, running rich, shit idle etc etc. ended up ditching it cause i cbf trying to rectify it. i have a feeling noss may have forgot to tune the chip for the rb25 afm but i understoodx he was/is busy and wasnt overly phased by it.
when hooking up the vg30 afm make sure the wires do in the correct spots too.
i thought you had fixed it? i had sent a few chips and had no response. there is a possibility it wasn't the right afm. there 6 different afms that are commonly used, z32 na, z32 turbo, rb25 na, rb25 turbo, rb20, maxima vg30 and then if you're a nutter the vq45 one.
anyway, if sss can't help you then you can send an email to
[email protected] which comes to my mobile phone so you'll be able to get me there, i'm not here much as because people have said, busy with work mostly and i'm just not having the time to get on here.
