Default Bigger maf?

Ok so I went forged 402 Ls2 with ported heads and a ported fast 90 and ported 90 mm throttle body....as I understand it the stock 02 Z06 maf is 85mm. The question is should I get a bigger maf? Im told that it will cause tuning problems or whatever......but it seems to me that leaving the stock 85mm in would be the bottleneck even though its FI

The way I understand it as long as your MAF is scaled correctly for your application, a larger MAF would be beneficial in reading a larger volume of air without maxxing out (12khz) the pcm's range. I intend to purchase either the proven LPE 100mm MAF or the new 103.5mm unit by Jim Hall
