Question about MAF A little help on this one....
Can I de-screen my stock MAF and not have to re-tune my on-board-puter or should I just buy an aftermarket one ??

Re: Question about MAF
If you descreen it will not read correctly and will lean you out...you need to get tuned
Didn't GM remove the screen from the Z06? Thread Starter

Re: Question about MAF
At a local dyno day, we descreened several MAFs and they didnt see an AF change, but did gain 2-3 RWHP just from that.

Re: Question about MAF In a perfect world, the maf tables in the PCM would need to be changed, but for most people on here you would just ending up running a little differently (might help, might hurt) if you don't tune.
You can see what GM themselves did when they removed the maf screen in 2002...they changed the maf table accordingly. The tables are listed here:
