My stock maf has been descreened and I have read that it is not good to do that. I was wondering if one from a corvette or camaro would work on it and if it would be worth getting.

 

just find a stock maf and you will be fine alot easier to tune as well.

 

You can tune a descreened MAF. You just need to do the SD tune to get your VE tables right and then turn the MAF back on to take logs so you can scale the MAF table.

If it were me, I would tune it rather than go spend more money and get ZERO performance gain.
