Car shudders when letting off the gas after MAFT and sensor install

[tom93vr4]

I don't have my maft installed yet, so maybe not much help but I do have a couple questions. You say it shudders when 'letting off the gas' - is this anytime, like driving down the highway with no boost or only from a wot pull or part throttle with lower boost? I assume your recirculating back into the stock recirc location at the bottom of the intake bubble? How close to this area is your gm maf installed?

SSQV recirculating.

GM sensor is in draw through (factory location). Seems to do it worse light load like when the cruise is trying to keep the same speed. But that might just be my perception. It does it 90%of the time regardless of its coming out of boost or never even was in boost.
