will be similar but still requires a maf scaling
also, with a turbo you shouldp probably take advance of hybrid speed density and not use maf at all during full throttle

you certanly want your tuner to tune it again after you change the maf from Draw through to Blow through

or at least ask him, he did the tune

I guess in the meantime I'll just have to drive it easy.

if he stays out of boost and wot he shoulfn t have any problem
anyway in open loop turbo benefits so much from speed density and then maf position is irrelevant

best way would be have your tuner ntroduce and scale speed density while your maf is in old position pre charger and then switch position

just be aware that the MAF sensor is also the intake air temp sensor, so chaging it from pre to post turbo will not only likely chage its maf scaling but also the measured intake air temps will be vastly different pre to post turbo

The set up i plan on having will have a bypass valve that sits right before the throttle body. This bypass valve will allow me to have an extra intake pipe so that when I'm not boosting the car can freely suck in air with no restriction. So not untill I get the car tuned would I have to worry about the charged temps affecting the MAF. But I will have to worry about the location since it will sit that much closer to the throttle body.
