Default Changing back to stock MAF

I know this may sound stupid but here it goes, Right now I am using a Gantanelli MAF its been on the car for years and runs great. But after reading all the bad post about them I am thinking of changing to a factory one. this is a new build and I had the car dyno tuned put down 446rwhp and 408rwtq question is do I need to have car retuned if I change the MAF out?
or do I just leave it alone.

I'd retune it.

From what I've seen those MAFs lean the mixture, so going back to the stocker will likely richen it up. Better yet, why not go to an 85mm setup?

what I meant was leave the set up alone with the granatelli MAF and just keep it my tune is spot on now. I guess after reading bad posts about them I'm a little paranoid.

^ agree 100%, If you are getting a good solid AFR all the way to redline there is no reason to "fix" it.

If it was tuned for the maf, then leave it in unless it causes drivability issues.


IF you change the maf it will need retuned.
