ive seen guys messin with a 4 inch card style mass air ls3/ls7 or somthing like has anyone tried this on the nnbs yet? if so will this affect in ant way cause ive done the 6l90 tranny conversion

 

the LS7 card will need the wiring diagram compared to your factory maf harness to make sure that you have the wires in the right spot. if you run a 4" maf, then you need to upgrade everything to 4" and it's well worth it

 

im trying to do the mass air ,4 inch intake, and fast truck intake all together.hopefully this will help,and im looking into if locking the converter will help and at gear and mph. Any expieriences with this would be appreciated thanks in advance

 

do u know a part number to which mass air is being used for the 4 inch?

 

Someone did a LS7 card an posted a p/n i think but i dont recall who.


That 4" will shine with the bigger intake. Are you doing a 102mm tb?

 

I think it was BlackGMC who did it but not 100% sure
