Random lean spike, could use some help... - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So here's the deal, I have a 2014 Camaro SS it has a bone stock LS3 (stock cam and all) I did a fuel system upgrade ID1000 injectors, Fore dual with return, flex fuel sensor. i updated the injector data and all was good, the car ran and drove like stock. I then installed a Kenne Bell 2.8 blower with a 4 1/2" intake and thats when the issue started. The issue I can't seem to fix is while driving at a steady speed I get random lean blips I can feel and see on the WB. For the lie of me I can't find the problem. I checked and double checked for vacuum leaks and found nothing.
If I disable the MAF the car runs great but no PE.
I'm stumped!

I see you changed the size of your intake I now wonder if you have altered the MAF signal by doing so... this can also affect the temperatures of the MAF leading to incorrect signals.

Did you rescale the maf?
