And sometimes in sounds like it's about 2 stall! Does any1 kno y this is happening??? Only mods I have r n upgraded ICP n intake can some1 please help wit this issue?? Thanx!

 

what intake? you might need a intake shield

 

Short ram K&N

 

This. The fan can blow on the open element and cause goofy maf readings.

 

So I pretty much need the intake shield??

 

The K&N intake includes a heatshield which also utilizes the stock snorkel, use it.
