Has anyone done any testing on GMS mass airflow sensor, such as before and after 0-60 and 1/4 mile times or dyno testing. I have one and I could barely tell a difference cause I also had a K&N FIPK put on right about the same time.
Thanks in advance.

 

i had one before i knew anything about it really.
i took it off and put the stock one back on back in the day and i didnt feel much of a difference between it and the stock MAF. From this board I've read it leans out the engine a great deal.
