I saw your post.
From what I extrapolated from your experiment, a bigger MAF is not necessarily better ; unless you have a stroker motor or possibly a H/C package.

Re: Ok, so is everybody agreed on the fact that the stock, gutted MAF is the best for i will concede that a properly tuned MAF is best in any situation. hogging one out and throwing it on is not good. even leaned out my 98.

Re: Ok, so is everybody agreed on the fact that the stock, gutted MAF is the best for What the post said was: From an airflow standpoint, there is no benefit to going to a ported stock MAF or 85mm MAF, even with a heads/cam motor like mine.
HOWEVER: I did pick up ET on my '98 Camaro and '00 WS6 by running ported stock MAFs. The reason I picked up ET, was not because of increased airflow, but because the motor liked the extra 3-4 degrees of timing. This was proved on the dyno and at the track. I went faster with ported MAFs...but again, it was because the motor liked the tune-up better, not because of the added-airflow.

Re: Ok, so is everybody agreed on the fact that the stock, gutted MAF is the best for IMHO a cheap way to get additional timing (if your engine needs it) is a ported stock maf. I like the 85mm screened maf for my car...part throttle A/F ratio's are dead on and the larger diameter flows well with the screen (also LPE picked up approx 5 ENGINE hp on their ASA engine with the 85mm screen maf vs the 75 mm screened maf...which would be 3 0r 4 rwhp). A no screen 75mm is probably close to a screened 85mm in flow.

Re: Ok, so is everybody agreed on the fact that the stock, gutted MAF is the best for From John Juriga GM Powertrain Cheif, commenting on the larger Truck MAF used in the 385 HP 2001 LS6:
"The other changes for the LS6 are the higher-capacity mass air flow (MAF) sensor from the 6.0-liter, Gen III truck engine. It’s worth 2-3hp and its integral intake air temperature (IAT) sensor simplifies the engine controls and reduces cost."
