Im having some bucking/hesitation under 2.5-3k rpms. I believe the Maf is to blame, I know there were all these threads with the testing of the land rover 82mm maf, but it is worth getting for my 3.5 4th gen, or just go with a regular 3.0 maf?

I havent looked into it much, the cost, etc...but do yo plan on going FI? Doesnt the 3.0 MAF only take like 300hp or something?

I plan on staying NA. I dunno how much the 3.0 maf can take.

My 3.0 maf has been taking 15psi of boost and not maxing out. If you arent going to boost or juice you will gain some but not much by going to a larger maf. Also if you do you need a afc of some sort and should have a wideband to make sure you arent running to lean.

I don't know if you can do a BBMAF with the VQ30 equipment, but apparently that yields some good results... http://forums.maxima.org/showthread.php?t=401373

Fo shizzle. Dont waste your money.

And you can do a bbmaf on vq30 with a afc. I have a q45 maf on my car now.

I have a VAFC2 and WB already, but I am staying NA. Do the BBMAF unit just plug right in or do I need the pigtail?

300zx maf

Youll need the pig tail. and yes the 300zx would be the best for you man. I only went with the q45 since it was cheaper and im fi . SO the bigger the better for me lol.

yet to be proven...

Its proven. Im not maxing out and i will never need to upgrade from this point. Thats proof enough.
