I just purshased a Granatelli Mass Air Flow Sensor and I was just wondering if other people have this and how mutch it helps thanx. . . .

 

Does not do much at all!

 

Works good but need to re program or engine will re calibrate A/F miture and can eventually change timing

 

I sent mine back two days after I got it. I really couldn't tell a difference, and it cost alot of money, so maybe my expectations were kinda high.

 

Borrowed one from a friend at the track and ran with and without it. Don't think i got even a full tenth outta it, but it's been a while since I did this so it's hard to remeber the times. in my opinion. I can't remember if i drove it all week before hand with it installed or not. I believe that i did though thinking the computer would learn it.

 

We recommend just keeping the stock one, it works just fine.

 

I've heard that the PCM actually leans the af ratio out when these are installed, which can cause pinging, which will lead to KR, which will take away power. Don't know first hand, just what I heard.

 

It is no magic silver bullet
