Im running a Granettelli MAF on my Magnacharge 5.3. When I installed it, it felt like the truck became a new animal. My con cern is that I may be running lean at full boost with the grannetelli after all is just a stock Maf ported and descreened. Whats your guys imput on this?

 

yeah it does make you run a little lean. good for stock but not with any mods. i switched back to the stock MAF after i installed the nitrous.

 

When you put the stock MAF back on, did you descreen it, or leave it undestroyed? lol

 

i left the screen on because i wanted to have the most accurate readings.
