I've been researching some cheap mods for my 2010 Silverado with the flex fuel 5.3L v8. I came across a thread where someone was talking about the ls7 MAf making a big difference in the way their truck ran. Is there any thruth to it? How could I go about installing one on my truck. I already have a MIT. And k&n drop in with the stock box and hptuners so I could tune the MAF based off the stft's.

 

In for the info. I know you need to get a bung to accept the card style MAF.

Part info from this thread

Bung: PN 19166574 and it runs $9.27
LS7 MAF PN: 15865791 and its $55.52

 

So the ls7 maf wont fit into the 2010 card maf slot? I was kinda hoping it would. But if i add the bung, how would I plug the factory hole? Or could I make it fit the factory hole?

 

I dont think it would fit based on the pix of the mafs


I have not looked at my 08 maf to check on plugging it up. Ill have to take a look.

 

You will need a tuner that knows how to tune for different MAFs. No way will it run right without a proper tune.

 

you have the same style maf as an ls7.

 

In for the info....

 

^This. I'm in the process of tuning mine and it's a bit of a headache. I have the card style MAF from an LS3 in a 4" intake I made myself.

 

09 and older gmt's had an maf housing, not a slide in card style.

 

I know, but since mine is a '10, I already have a card style maf. I was just wondering how hard it would be to adapt the ls7 maf into the stock hole...
