On a forced induction build for a n/a 996, I've seen resistors being used to modify the mass air flow signal. If tuning on a dyno, is there any reason not to use an alternative like an OE 996 turbo MAF sensor, or new programmable meter. ?

 

yyyuucccckk. that sounds like a really ghetto way to tune the car. You're much better off using an OE turbo MAF or something else that is actually designed to meter more air, with a properly programmed ECU
